==地球系统科学读书会简介==
地球科学是研究相互作用的大气圈、水圈、岩石圈和生物圈等组成的地球系统的形成、演化机制的学科。地球系统科学的研究对象是一个复杂的物理系统，从远古时代，人类便观察到一些独特的自然现象，在生产生活实践中，也尝试理解地球系统不同组成要素的联系，渐渐总结出了看云识天气，瑞雪兆丰年等一些列规律。

但是这些经验化的规律并不能完全刻画地球系统的变化，随着现代科学的不断发展，科学家尝试对复杂的地球系统进行定量化的研究。地球的气候系统是众多的复杂系统之一，在 20 世纪 60 年代，美国气象学家真锅淑郎开始探索大气中辐射平衡与气团垂直输送之间相互作用，据此领导了第一个地球气候物理模型的开发，并展示了大气中二氧化碳浓度的增加如何导致地球表面温度升高。大约十年后，德国气象学家克劳斯·哈塞尔曼创建了一个将天气和气候联系在一起的模型，并进一步回答了尽管天气多变而混沌，但气候模型却仍然可靠。此外他还开发了识别特定信号和印记（指纹）的方法，发现自然过程和人类活动都会在气候变化中留下指纹，证明了第一次工业革命以来大气温度的快速升高主要是是由人类排放二氧化碳导致的。这些开创性的工作，也让真锅淑郎和克劳斯·哈塞尔曼获得了2021年的诺贝尔物理学奖。

全球变暖显著地改变了地球系统的演化过程，由此引发的冰川退缩，海平面上升，极端天气气候事件频发等一系列的环境灾害，给人类社会也带来了许多严重的灾难。因此全球变暖不仅仅是一个科学前沿问题，更是一个重要的社会政治问题，影响着每个人的生存和发展。随着站点观测，卫星遥感、雷达等大量观测平台的相继建设，也产生了海量的地球系统观测数据，而目前经典的物理模型往往不能充分地利用这些数据，地球系统的许多问题也急需新的方法来深入解决。基于复杂网络的分析方法近些年来也被广泛运用，在中短期天气预报，二氧化碳空间不均匀分布的增暖效应，以及火灾的预测等问题上有了很多的创新性的工作。

此外，随着计算机技术、人工智能的快速发展，许多深度学习的方法比如神经网络、图网络等也被广泛地应用于分析和解决许多的地球系统科学问题，目前在大气污染预报，厄尔尼诺预测，自然灾害损失评估等领域有了明显的进展。复杂网络，深度学习等新方法的成功运用，给地球系统科学这门古老的学科注入了新的发展动力，也为解决当前地球系统科学面临的许多问题和迎接未来的挑战提供了强大动能。

由中国地质大学特聘副教授邓琪敏，北京师范大学“励耘”博士后，助理研究员张钢锋，北京师范大学系统科学学院在读博士王硕、在读硕士许菁等人发起的「地球系统科学」系列读书会，将组织大家系统地研究这些以统计物理方法、深度学习方法为核心在地球系统科学中应用的相关文献，深入研读相关文献，激发科研灵感。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected. For example, the movement of water is critical for leaching sulfur and phosphorus into rivers which can then flow into oceans. Minerals cycle through the biosphere between the biotic and abiotic components and from one organism to another.<ref name=Fisher2019>Fisher M. R. (Ed.)

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

The diagram on the right shows a generalised biogeochemical cycle. The major parts of the biosphere are connected by the flow of chemical elements and compounds. In many of these cycles, the biota plays an important role. Matter from the Earth's interior is released by volcanoes. The atmosphere exchanges some compounds and elements rapidly with the biota and oceans. Exchanges of materials between rocks, soils, and the oceans are generally slower by comparison.<ref name=Moses2012>Moses, M.

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。

Box models are widely used to model biogeochemical systems.Bianchi, Thomas (2007) Biogeochemistry of Estuaries page 9, Oxford University Press. . Box models are simplified versions of complex systems, reducing them to boxes (or storage reservoirs) for chemical materials, linked by material fluxes (flows). Simple box models have a small number of boxes with properties, such as volume, that do not change with time. The boxes are assumed to behave as if they were mixed homogeneously. These models are often used to derive analytical formulas describing the dynamics and steady-state abundance of the chemical species involved.

箱模型被广泛用于生物地球化学系统建模。箱模型是复杂系统的简化版本，将其简化为存放化学物质的箱（或储库），并由物质通量（流）进行连接。简单的箱模型含有少量属性不随时间变化的箱室，例如体积。这些箱室的行为被假定为是均匀混合的。这些模型经常被用于推导出解析公式以描述所涉及的化学物质的动力学和稳态丰度。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a steady state if Q = S, that is, if the sources balance the sinks and there is no change over time.

右图展示了一个基本的单箱模型。储库包含了所考虑的物质M的量，按照化学、物理或生物属性的定义。源Q是流入储库的物质通量，汇S是流出储库的物质通量。预算是影响储库内物质周转的源和汇的制衡。当Q = S，即源与汇处于平衡状态且不随时间变化时，储库处于稳态。

The residence or turnover time is the average time material spends resident in the reservoir. If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S.<ref name=Bianchi2007 /> The equation describing the rate of change of content in a reservoir is

The residence or turnover time is the average time material spends resident in the reservoir. If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S. The equation describing the rate of change of content in a reservoir is

停留时间或周转时间是物质在储库中停留的平均时间。如果储库处于稳态，其等于蓄满或排空储库所需的时间。因此，如果τ 是周转时间，那么 τ = M/S。描述储库物质含量变化率的方程为

::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>

:: \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}

* frac { dM }{ dt } = q-s = q-frac { m }{ tau }

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow.<ref name=Bianchi2007 /> More complex [[multi-compartment model|multibox models]] are usually solved using numerical techniques.

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow. More complex multibox models are usually solved using numerical techniques.

当两个或多个储库相连通时，可以认为物质在储库之间循环，且循环流动具有可预测的模式。更复杂的多箱模型通常用数值方法求解。

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the [[Industrial Revolution]]. The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

The global ocean covers more than 70% of the Earth's surface and is remarkably heterogeneous. Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

Global change is, therefore, affecting key processes including primary productivity, CO2 and N2 fixation, organic matter respiration/remineralization, and the sinking and burial deposition of fixed CO2. In addition to this, oceans are experiencing an acidification process, with a change of ~0.1 pH units between the pre-industrial period and today, affecting carbonate/bicarbonate buffer chemistry.

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and [[seafloor sediments]]. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition.

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide.

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储库，含有14-135Pg的碳和总生物量的2-19%。微生物在这种环境下驱动有机和无机化合物的转化，从而控制生物地球化学循环。目前对于地下微生物生态学的了解主要是基于16S核糖体RNA（rRNA）基因序列。最近的估计显示，公共数据库中小于8%的16S rRNA序列来自于地下生物，且其中仅一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上互相关联的，我们知之甚少。一些基于栽培的同养群落研究和对自然群落的小规模宏基因组学分析表明，生物体通过代谢传递相联系：一个生物的氧化还原产物转移到另一生物。然而，还没有一个复杂的环境被彻底剖析，以解决支撑它们的代谢相互作用网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。新的方法，如基因组解析宏基因组学，可以在无需实验室分离的情况下为生物体提供一套全面的草图甚至是完整的基因组，这种方法或许是理解生物地球化学过程的关键。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected. For example, the movement of water is critical for leaching sulfur and phosphorus into rivers which can then flow into oceans. Minerals cycle through the biosphere between the biotic and abiotic components and from one organism to another.<ref name=Fisher2019>Fisher M. R. (Ed.)

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

The diagram on the right shows a generalised biogeochemical cycle. The major parts of the biosphere are connected by the flow of chemical elements and compounds. In many of these cycles, the biota plays an important role. Matter from the Earth's interior is released by volcanoes. The atmosphere exchanges some compounds and elements rapidly with the biota and oceans. Exchanges of materials between rocks, soils, and the oceans are generally slower by comparison.<ref name=Moses2012>Moses, M.

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

Biogeochemical cycles can be contrasted with [[geochemical cycle]]s. The latter deals only with [[Earth's crust|crustal]] and subcrustal reservoirs even though some process from both overlap.

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。

箱模型被广泛用于生物地球化学系统建模。箱模型是复杂系统的简化版本，将其简化为存放化学物质的箱（或储库），并由物质通量（流）进行连接。简单的箱模型含有少量属性不随时间变化的箱室，例如体积。这些箱室的行为被假定为是均匀混合的。这些模型经常被用于推导出解析公式以描述所涉及的化学物质的动力学和稳态丰度。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir.

The reservoir is in a steady state if Q = S, that is, if the sources balance the sinks and there is no change over time.

右图展示了一个基本的单箱模型。储库包含了所考虑的物质M的量，按照化学、物理或生物属性的定义。源Q是流入储库的物质通量，汇S是流出储库的物质通量。预算是影响储库内物质周转的源和汇的制衡。当Q = S，即源与汇处于平衡状态且不随时间变化时，储库处于稳态。

The residence or turnover time is the average time material spends resident in the reservoir. If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S.<ref name=Bianchi2007 /> The equation describing the rate of change of content in a reservoir is

The equation describing the rate of change of content in a reservoir is

停留时间或周转时间是物质在储库中停留的平均时间。如果储库处于稳态，其等于蓄满或排空储库所需的时间。因此，如果τ 是周转时间，那么 τ = M/S。描述储库物质含量变化率的方程为

::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>

:: \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}

* frac { dM }{ dt } = q-s = q-frac { m }{ tau }

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow.<ref name=Bianchi2007 /> More complex [[multi-compartment model|multibox models]] are usually solved using numerical techniques.

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow. More complex multibox models are usually solved using numerical techniques.

当两个或多个储库相连通时，可以认为物质在储库之间循环，且循环流动具有可预测的模式。更复杂的多箱模型通常用数值方法求解。

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the [[Industrial Revolution]]. The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

The global ocean covers more than 70% of the Earth's surface and is remarkably heterogeneous. Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and [[seafloor sediments]]. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition. The reactions of the fast carbon cycle to human activities will determine many of the more immediate impacts of climate change.<ref name=Bush2020 /><ref>{{cite journal |doi = 10.1073/pnas.022055499|title = Atmospheric carbon dioxide levels for the last 500 million years|year = 2002|last1 = Rothman|first1 = D.

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels.<ref name=Libes2015 /><ref name="Bush2020">{{cite book|doi = 10.1007/978-3-030-15424-0_3|url = https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|title = Climate Change and Renewable Energy|year = 2020|last1 = Bush|first1 = Martin J.|pages = 109–141|isbn = 978-3-030-15423-3|s2cid = 210305910|access-date = 2021-09-27|archive-date = 2021-09-27|archive-url = https://web.archive.org/web/20210927001642/https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|url-status = live}}</ref>

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储库，含有14-135Pg的碳和总生物量的2-19%。微生物在这种环境下驱动有机和无机化合物的转化，从而控制生物地球化学循环。目前对于地下微生物生态学的了解主要是基于16S核糖体RNA（rRNA）基因序列。最近的估计显示，公共数据库中小于8%的16S rRNA序列来自于地下生物，且其中仅一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上互相关联的，我们知之甚少。一些基于栽培的同养群落研究和对自然群落的小规模宏基因组学分析表明，生物体通过代谢传递相联系：一个生物的氧化还原产物转移到另一生物。然而，还没有一个复杂的环境被彻底剖析，以解决支撑它们的代谢相互作用网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。新的方法，如基因组解析宏基因组学，可以在无需实验室分离的情况下为生物体提供一套全面的草图甚至是完整的基因组，这种方法或许是理解生物地球化学过程的关键。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins.

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins.

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

Biogeochemical cycles can be contrasted with [[geochemical cycle]]s. The latter deals only with [[Earth's crust|crustal]] and subcrustal reservoirs even though some process from both overlap.

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean.

The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period.

The global ocean covers more than 70% of the Earth's surface and is remarkably heterogeneous. Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and [[seafloor sediments]]. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition.

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储库，含有14-135Pg的碳和总生物量的2-19%。微生物在这种环境下驱动有机和无机化合物的转化，从而控制生物地球化学循环。目前对于地下微生物生态学的了解主要是基于16S核糖体RNA（rRNA）基因序列。最近的估计显示，公共数据库中小于8%的16S rRNA序列来自于地下生物，且其中仅一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上互相关联的，我们知之甚少。一些基于栽培的同养群落研究和对自然群落的小规模宏基因组学分析表明，生物体通过代谢传递相联系：一个生物的氧化还原产物转移到另一生物。然而，还没有一个复杂的环境被彻底剖析，以解决支撑它们的代谢相互作用网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。新的方法，如基因组解析宏基因组学，可以在无需实验室分离的情况下为生物体提供一套全面的草图甚至是完整的基因组，这种方法或许是理解生物地球化学过程的关键。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected. For example, the movement of water is critical for leaching sulfur and phosphorus into rivers which can then flow into oceans.

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

The diagram on the right shows a generalised biogeochemical cycle. The major parts of the biosphere are connected by the flow of chemical elements and compounds. In many of these cycles, the biota plays an important role. Matter from the Earth's interior is released by volcanoes. The atmosphere exchanges some compounds and elements rapidly with the biota and oceans.

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

Biogeochemical cycles can be contrasted with [[geochemical cycle]]s. The latter deals only with [[Earth's crust|crustal]] and subcrustal reservoirs even though some process from both overlap.

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

The residence or turnover time is the average time material spends resident in the reservoir.

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

In the euphotic zone, net phytoplankton production is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as particles (marine snow) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the [[Industrial Revolution]]. The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change.

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

Global change is, therefore, affecting key processes including primary productivity, CO2 and N2 fixation, organic matter respiration/remineralization, and the sinking and burial deposition of fixed CO2. In addition to this, oceans are experiencing an acidification process, with a change of ~0.1 pH units between the pre-industrial period and today, affecting carbonate/bicarbonate buffer chemistry. In turn, acidification has been reported to impact planktonic communities, principally through effects on calcifying taxa. There is also evidence for shifts in the production of key intermediary volatile products, some of which have marked greenhouse effects (e.g., N2O and CH4, reviewed by Breitburg in 2018, due to the increase in global temperature, ocean stratification and deoxygenation, driving as much as 25 to 50% of nitrogen loss from the ocean to the atmosphere in the so-called oxygen minimum zones or anoxic marine zones, driven by microbial processes. Other products, that are typically toxic for the marine nekton, including reduced sulfur species such as H2S, have a negative impact for marine resources like fisheries and coastal aquaculture. While global change has accelerated, there has been a parallel increase in awareness of the complexity of marine ecosystems, and especially the fundamental role of microbes as drivers of ecosystem functioning.

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

There are fast and slow biogeochemical cycles. Fast cycle operate in the biosphere and slow cycles operate in rocks. Fast or biological cycles can complete within years, moving substances from atmosphere to biosphere, then back to the atmosphere. Slow or geological cycles can take millions of years to complete, moving substances through the Earth's crust between rocks, soil, ocean and atmosphere.Libes, Susan M. (2015).

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term biogeochemical processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and seafloor sediments. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition. The reactions of the fast carbon cycle to human activities will determine many of the more immediate impacts of climate change. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels.<ref name=Libes2015 /><ref name="Bush2020">{{cite book|doi = 10.1007/978-3-030-15424-0_3|url = https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|title = Climate Change and Renewable Energy|year = 2020|last1 = Bush|first1 = Martin J.|pages = 109–141|isbn = 978-3-030-15423-3|s2cid = 210305910|access-date = 2021-09-27|archive-date = 2021-09-27|archive-url = https://web.archive.org/web/20210927001642/https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|url-status = live}}</ref>

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储库，含有14-135Pg的碳和总生物量的2-19%。微生物在这种环境下驱动有机和无机化合物的转化，从而控制生物地球化学循环。目前对于地下微生物生态学的了解主要是基于16S核糖体RNA（rRNA）基因序列。最近的估计显示，公共数据库中小于8%的16S rRNA序列来自于地下生物，且其中仅一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上互相关联的，我们知之甚少。一些基于栽培的同养群落研究和对自然群落的小规模宏基因组学分析表明，生物体通过代谢传递相联系：一个生物的氧化还原产物转移到另一生物。然而，还没有一个复杂的环境被彻底剖析，以解决支撑它们的代谢相互作用网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。新的方法，如基因组解析宏基因组学，可以在无需实验室分离的情况下为生物体提供一套全面的草图甚至是完整的基因组，这种方法或许是理解生物地球化学过程的关键。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected. For example, the movement of water is critical for leaching sulfur and phosphorus into rivers which can then flow into oceans. Minerals cycle through the biosphere between the biotic and abiotic components and from one organism to another.<ref name=Fisher2019>Fisher M. R. (Ed.)

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

The diagram on the right shows a generalised biogeochemical cycle. The major parts of the biosphere are connected by the flow of chemical elements and compounds. In many of these cycles, the biota plays an important role. Matter from the Earth's interior is released by volcanoes. The atmosphere exchanges some compounds and elements rapidly with the biota and oceans. Exchanges of materials between rocks, soils, and the oceans are generally slower by comparison.<ref name=Moses2012>Moses, M.

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

The chemicals are sometimes held for long periods of time in one place.

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。

箱模型被广泛用于生物地球化学系统建模。箱模型是复杂系统的简化版本，将其简化为存放化学物质的箱（或储库），并由物质通量（流）进行连接。简单的箱模型含有少量属性不随时间变化的箱室，例如体积。这些箱室的行为被假定为是均匀混合的。这些模型经常被用于推导出解析公式以描述所涉及的化学物质的动力学和稳态丰度。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

右图展示了一个基本的单箱模型。储库包含了所考虑的物质M的量，按照化学、物理或生物属性的定义。源Q是流入储库的物质通量，汇S是流出储库的物质通量。预算是影响储库内物质周转的源和汇的制衡。当Q = S，即源与汇处于平衡状态且不随时间变化时，储库处于稳态。

The residence or turnover time is the average time material spends resident in the reservoir. If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S.<ref name=Bianchi2007 /> The equation describing the rate of change of content in a reservoir is

If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S. The equation describing the rate of change of content in a reservoir is

停留时间或周转时间是物质在储库中停留的平均时间。如果储库处于稳态，其等于蓄满或排空储库所需的时间。因此，如果τ 是周转时间，那么 τ = M/S。描述储库物质含量变化率的方程为

::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>

:: \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}

* frac { dM }{ dt } = q-s = q-frac { m }{ tau }

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow.<ref name=Bianchi2007 /> More complex [[multi-compartment model|multibox models]] are usually solved using numerical techniques.

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow. More complex multibox models are usually solved using numerical techniques.

当两个或多个储库相连通时，可以认为物质在储库之间循环，且循环流动具有可预测的模式。更复杂的多箱模型通常用数值方法求解。

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the [[Industrial Revolution]]. The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

Global change is, therefore, affecting key processes including primary productivity, CO2 and N2 fixation, organic matter respiration/remineralization, and the sinking and burial deposition of fixed CO2. In addition to this, oceans are experiencing an acidification process, with a change of ~0.1 pH units between the pre-industrial period and today, affecting carbonate/bicarbonate buffer chemistry. In turn, acidification has been reported to impact planktonic communities, principally through effects on calcifying taxa. There is also evidence for shifts in the production of key intermediary volatile products, some of which have marked greenhouse effects (e.g., N2O and CH4, reviewed by Breitburg in 2018, due to the increase in global temperature, ocean stratification and deoxygenation, driving as much as 25 to 50% of nitrogen loss from the ocean to the atmosphere in the so-called oxygen minimum zones or anoxic marine zones, driven by microbial processes. Other products, that are typically toxic for the marine nekton, including reduced sulfur species such as H2S, have a negative impact for marine resources like fisheries and coastal aquaculture.

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and [[seafloor sediments]]. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition.

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide.

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储库，含有14-135Pg的碳和总生物量的2-19%。微生物在这种环境下驱动有机和无机化合物的转化，从而控制生物地球化学循环。目前对于地下微生物生态学的了解主要是基于16S核糖体RNA（rRNA）基因序列。最近的估计显示，公共数据库中小于8%的16S rRNA序列来自于地下生物，且其中仅一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上互相关联的，我们知之甚少。一些基于栽培的同养群落研究和对自然群落的小规模宏基因组学分析表明，生物体通过代谢传递相联系：一个生物的氧化还原产物转移到另一生物。然而，还没有一个复杂的环境被彻底剖析，以解决支撑它们的代谢相互作用网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。新的方法，如基因组解析宏基因组学，可以在无需实验室分离的情况下为生物体提供一套全面的草图甚至是完整的基因组，这种方法或许是理解生物地球化学过程的关键。

Biogeochemical cycles always involve active equilibrium states: a balance in the cycling of the element between compartments. However, overall balance may involve compartments distributed on a global scale.

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three-dimensional shape of proteins. The cycling of these elements is interconnected. For example, the movement of water is critical for leaching sulfur and phosphorus into rivers which can then flow into oceans. Minerals cycle through the biosphere between the biotic and abiotic components and from one organism to another.<ref name=Fisher2019>Fisher M. R. (Ed.)

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

The diagram on the right shows a generalised biogeochemical cycle. The major parts of the biosphere are connected by the flow of chemical elements and compounds. In many of these cycles, the biota plays an important role. Matter from the Earth's interior is released by volcanoes. The atmosphere exchanges some compounds and elements rapidly with the biota and oceans. Exchanges of materials between rocks, soils, and the oceans are generally slower by comparison.<ref name=Moses2012>Moses, M.

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。

Biogeochemical cycles can be contrasted with [[geochemical cycle]]s. The latter deals only with [[Earth's crust|crustal]] and subcrustal reservoirs even though some process from both overlap.

Biogeochemical cycles can be contrasted with geochemical cycles. The latter deals only with crustal and subcrustal reservoirs even though some process from both overlap.

生物地球化学循环可以与地球化学循环形成对比。尽管两者的部分过程是重叠的，地球化学循环仅涉及地壳和地下储库。

== Reservoirs ==
The chemicals are sometimes held for long periods of time in one place. This place is called a ''reservoir'', which, for example, includes such things as [[coal]] deposits that are storing [[carbon]] for a long period of time.<ref name="carbon">{{cite web|last1=Baedke|first1=Steve J.|last2=Fichter|first2=Lynn S.|title=Biogeochemical Cycles: Carbon Cycle|url=http://csmgeo.csm.jmu.edu/geollab/idls/carboncycle.htm|website=Supplimental Lecture Notes for Geol 398|publisher=James Madison University|access-date=20 November 2017|archive-date=1 December 2017|archive-url=https://web.archive.org/web/20171201043948/http://csmgeo.csm.jmu.edu/geollab/idls/carboncycle.htm|url-status=live}}</ref> When chemicals are held for only short periods of time, they are being held in ''exchange pools''.

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。

箱模型被广泛用于生物地球化学系统建模。箱模型是复杂系统的简化版本，将其简化为存放化学物质的箱（或储库），并由物质通量（流）进行连接。简单的箱模型含有少量属性不随时间变化的箱室，例如体积。这些箱室的行为被假定为是均匀混合的。这些模型经常被用于推导出解析公式以描述所涉及的化学物质的动力学和稳态丰度。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a [[steady state]] if ''Q'' = ''S'', that is, if the sources balance the sinks and there is no change over time.<ref name=Bianchi2007 />

The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir.

右图展示了一个基本的单箱模型。储库包含了所考虑的物质M的量，按照化学、物理或生物属性的定义。源Q是流入储库的物质通量，汇S是流出储库的物质通量。预算是影响储库内物质周转的源和汇的制衡。当Q = S，即源与汇处于平衡状态且不随时间变化时，储库处于稳态。

The residence or turnover time is the average time material spends resident in the reservoir. If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S.<ref name=Bianchi2007 /> The equation describing the rate of change of content in a reservoir is

If the reservoir is in a steady state, this is the same as the time it takes to fill or drain the reservoir. Thus, if τ is the turnover time, then τ = M/S. The equation describing the rate of change of content in a reservoir is

停留时间或周转时间是物质在储库中停留的平均时间。如果储库处于稳态，其等于蓄满或排空储库所需的时间。因此，如果τ 是周转时间，那么 τ = M/S。描述储库物质含量变化率的方程为

::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>

:: \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}

* frac { dM }{ dt } = q-s = q-frac { m }{ tau }

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow.<ref name=Bianchi2007 /> More complex [[multi-compartment model|multibox models]] are usually solved using numerical techniques.

When two or more reservoirs are connected, the material can be regarded as cycling between the reservoirs, and there can be predictable patterns to the cyclic flow. More complex multibox models are usually solved using numerical techniques.

当两个或多个储库相连通时，可以认为物质在储库之间循环，且循环流动具有可预测的模式。更复杂的多箱模型通常用数值方法求解。

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr-1被埋藏并从生物圈转移到地圈。

The diagram on the right above shows a more complex model with many interacting boxes. Reservoir masses here represents ''carbon stocks'', measured in Pg C. Carbon exchange fluxes, measured in Pg C yr−1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the [[Industrial Revolution]]. The red arrows (and associated numbers) indicate the annual flux changes due to anthropogenic activities, averaged over the 2000–2009 time period. They represent how the carbon cycle has changed since 1750. Red numbers in the reservoirs represent the cumulative changes in anthropogenic carbon since the start of the Industrial Period, 1750–2011.<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

The global ocean covers more than 70% of the Earth's surface and is remarkably heterogeneous. Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

海洋覆盖了地球表面的70%以上，并且具有很强的异质性。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但对微生物群落（占海洋生物量的90%）所进行的全球生物地球化学循环有着巨大的影响。近年来的工作主要集中在碳和常量营养元素（如氮、磷和硅酸盐）的循环上，对其它重要元素（如硫或微量元素）的研究较少，反映的相关的技术和后勤问题。这些海域以及构成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。一个关键的例子是人为富营养化的影响，农业生产的径流导致沿海生态系统的氮和磷富集，使生产力大大提高并造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，直接影响了区域和全球的氮循环和碳循环。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列胁迫之一。气候变化还导致了冰冻圈的变化，冰川和永久冻土融化加剧了海洋分层，而不同生物群落中氧化还原状态的变化正以前所未有的速度迅速重塑微生物组合。

因此，全球变化正在影响着关键过程，包括净初级生产力，CO2和N2固定，有机物呼吸/再矿化以及固定CO2的沉积和埋藏。除此之外，海洋正在经历酸化过程，从前工业化时期到如今pH值变化了约0.1个单位，影响了碳酸盐和碳酸氢盐缓冲的化学过程。反过来，酸化主要通过对钙化类群的影响从而影响浮游生物群落。还有证据表明，关键的中间挥发性产物的生产过程发生了变化，其中一些产物具有明显的温室效应（例如N2O和CH4，Breitburg在2018年的综述中所言。由于全球温度升高，海洋分层和脱氧，在所谓的最低含氧区或缺氧海洋区由于微生物的驱动导致大洋中25%-50%的氮损失到大气中）。其它对海洋自游生物有毒的产物，包括诸如H2S等硫的还原产物，对渔业和沿海水产养殖等海洋资源有负面影响。虽然全球变化加速，但人们对海洋生态系统复杂性的认识也在同步提高，尤其是微生物作为生态系统功能驱动因素的基本作用。

生物地球化学循环包括快速和慢速循环。快速循环在生物圈中运行，慢速循环在岩石中运行。快速循环或生物循环可以在数年内完成，将物质从大气转移到生物圈，再转移到大气。慢速或地质循环可能需要数百万年才能完成，使物质穿过岩石、土壤、海洋和大气在地壳中运移。.

As an example, the fast carbon cycle is illustrated in the diagram below on the left. This cycle involves relatively short-term [[biogeochemical]] processes between the environment and living organisms in the biosphere. It includes movements of carbon between the atmosphere and terrestrial and marine ecosystems, as well as soils and [[seafloor sediments]]. The fast cycle includes annual cycles involving photosynthesis and decadal cycles involving vegetative growth and decomposition. The reactions of the fast carbon cycle to human activities will determine many of the more immediate impacts of climate change.<ref name=Bush2020 /><ref>{{cite journal |doi = 10.1073/pnas.022055499|title = Atmospheric carbon dioxide levels for the last 500 million years|year = 2002|last1 = Rothman|first1 = D.

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels.<ref name=Libes2015 /><ref name="Bush2020">{{cite book|doi = 10.1007/978-3-030-15424-0_3|url = https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|title = Climate Change and Renewable Energy|year = 2020|last1 = Bush|first1 = Martin J.|pages = 109–141|isbn = 978-3-030-15423-3|s2cid = 210305910|access-date = 2021-09-27|archive-date = 2021-09-27|archive-url = https://web.archive.org/web/20210927001642/https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|url-status = live}}</ref>

缓慢的循环在上面右边的图表中显示出来。它涉及中长期的地球化学过程，属于岩石旋回。海洋和大气之间的交换可能需要几个世纪，岩石的风化可能需要几百万年。海洋中的碳沉淀到海底，在那里它可以形成沉积岩并潜入地幔。造山过程导致这种地质碳返回到地球表面。在那里，岩石被风化，碳通过排气返回大气层，通过河流流入海洋。其他地质碳通过钙离子的水热释放返回海洋。在给定的一年中，1000万到1亿吨的碳在这个缓慢的循环周期中移动。这包括火山以二氧化碳的形式将地质碳直接返回大气层。然而，这还不到燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储存库，含有14-135 Pg 的碳，占所有生物量的2-19% 。微生物在这种环境中推动有机和无机化合物的转变，从而控制生物地球化学循环。目前对地下微生物生态学的了解主要是基于16S 核糖体RNA 基因序列。最近的估计显示，公共数据库中的16s rRNA 序列中，少于8% 来自地下生物，其中只有一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上相互关联的，我们知之甚少。一些以培养为基础的联合营养研究和对自然群落的小规模宏基因组学分析表明，生物体之间是通过代谢传递联系起来的: 一种生物体的氧化还原反应产物转移到另一种生物体。然而，还没有一个复杂的环境被彻底剖析，足以解析支撑它们的代谢交互网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。基因组分解宏基因组学等新的方法可以为生物体提供一套全面的草图甚至完整的基因组，而不需要实验室隔离，这种方法有可能提供对生物地球化学过程的这一关键水平的理解。50px 材料复制自这个来源，可以在知识共享署名4.0国际许可证下获得。

A '''biogeochemical cycle''' is the pathway by which a [[chemical substance]] [[Wiktionary:cycle|cycles]] (is turned over or moves through) the [[Biotic components|biotic]] and the [[abiotic]] compartments of [[Earth]]. The biotic compartment is the [[biosphere]] and the abiotic compartments are the [[atmosphere]], [[hydrosphere]] and [[lithosphere]]. There are [[biogeochemistry|biogeochemical]] cycles for chemical elements, such as for [[calcium cycle|calcium]], [[carbon cycle|carbon]], [[hydrogen cycle|hydrogen]], [[mercury cycle|mercury]], [[nitrogen cycle|nitrogen]], [[oxygen cycle|oxygen]], [[phosphorus cycle|phosphorus]], [[selenium cycle|selenium]], [[iron cycle|iron]] and [[sulfur cycle|sulfur]], as well as molecular cycles, such as for [[water cycle|water]] and [[silica cycle|silica]]. There are also macroscopic cycles, such as the [[rock cycle]], and human-induced cycles for synthetic compounds such as [[polychlorinated biphenyl]]s (PCBs). In some cycles there are reservoirs where a substance can remain or be [[:Wiktionary:sequestered|sequestered]] for a long period of time.

A biogeochemical cycle is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium, carbon, hydrogen, mercury, nitrogen, oxygen, phosphorus, selenium, iron and sulfur, as well as molecular cycles, such as for water and silica. There are also macroscopic cycles, such as the rock cycle, and human-induced cycles for synthetic compounds such as polychlorinated biphenyls (PCBs). In some cycles there are reservoirs where a substance can remain or be sequestered for a long period of time.

生物地球化学循环是化学物质在地球的生物部分和非生物部分中进行循环（被转化或穿过）的过程。生物部分指生物圈，非生物部分指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins.

The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins.

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。

Ecological systems ([[ecosystem]]s) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water ([[hydrosphere]]), land ([[lithosphere]]), and/or the air ([[atmosphere]]).<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>

在生态系统（ecosystems）中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as [[carbon]], [[nitrogen]], [[oxygen]], [[phosphorus]], and [[sulfur]]—used in ecosystems by living organisms are a part of a ''closed system''; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.<ref name="enviroliteracy.org"/>

地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。

右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

The flow of energy in an ecosystem is an ''open system''; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the [[trophic level]]s of a food web. Carbon is used to make carbohydrates, fats, and proteins, the major sources of [[food energy]]. These compounds are oxidized to release carbon dioxide, which can be captured by plants to make organic compounds. The [[chemical reaction]] is powered by the light energy of the sun.

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

Sunlight is required to combine carbon with hydrogen and oxygen into an energy source, but ecosystems in the [[deep sea]], where no sunlight can penetrate, obtain energy from sulfur. [[Hydrogen sulfide]] near [[hydrothermal vent]]s can be utilized by organisms such as the [[giant tube worm]]. In the [[sulfur cycle]], sulfur can be forever recycled as a source of energy. Energy can be released through the [[oxidation]] and [[redox|reduction]] of sulfur compounds (e.g., oxidizing elemental sulfur to [[sulfite]] and then to [[sulfate]]).

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

Although the Earth constantly receives energy from the sun, its chemical composition is essentially fixed, as the additional matter is only occasionally added by meteorites. Because this chemical composition is not replenished like energy, all processes that depend on these chemicals must be recycled. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere.

虽然地球不断地从太阳那里获得能量，但其化学成份基本上是固定的，因为额外的物质只是偶尔被陨石添加进来。因为这些化学成份不像能源那样得到补充，所以所有依赖这些化学物质的过程都必须被回收。这些循环包括活生生的生物圈和无生命的岩石圈、大气圈和水圈。

The chemicals are sometimes held for long periods of time in one place. This place is called a reservoir, which, for example, includes such things as coal deposits that are storing carbon for a long period of time. When chemicals are held for only short periods of time, they are being held in exchange pools. Examples of exchange pools include plants and animals.

这些化学品有时在一个地方放置很长时间。这个地方被称为一个水库，例如，这个水库包括一些煤矿，这些煤矿可以长时间储存碳。当化学品只持有很短一段时间时，它们就被存放在交换池中。交换池的例子包括植物及动物。

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy. Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. Carbon is held for a relatively short time in plants and animals in comparison to coal deposits. The amount of time that a chemical is held in one place is called its [[residence time]] or [[turnover time]] (also called the renewal time or exit age).<ref name="carbon" />

植物和动物利用碳来生产碳水化合物、脂肪和蛋白质，这些物质可以用来建立它们的内部结构或获得能量。植物和动物暂时使用它们系统中的碳，然后释放到空气中或周围的介质。一般来说，储层是非生物因素，而交换池是生物因素。与煤层相比，动植物体内的碳储存时间相对较短。一种化学品在一个地方停留的时间称为停留时间或周转时间(也称为更新时间或退出时间)。

The diagram at the right shows a basic one-box model. The reservoir contains the amount of material ''M'' under consideration, as defined by chemical, physical or biological properties. The source ''Q'' is the flux of material into the reservoir, and the sink ''S'' is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir.

The diagram on the left above shows a simplified budget of ocean carbon flows. It is composed of three simple interconnected box models, one for the [[euphotic zone]], one for the [[Aphotic zone|ocean interior]] or dark ocean, and one for [[ocean sediment]]s. In the euphotic zone, net [[phytoplankton production]] is about 50 Pg C each year. About 10 Pg is exported to the ocean interior while the other 40 Pg is respired. Organic carbon degradation occurs as [[Particulate organic carbon|particles]] ([[marine snow]]) settle through the ocean interior. Only 2 Pg eventually arrives at the seafloor, while the other 8 Pg is respired in the dark ocean. In sediments, the time scale available for degradation increases by orders of magnitude with the result that 90% of the organic carbon delivered is degraded and only 0.2 Pg C yr−1 is eventually buried and transferred from the biosphere to the geosphere.<ref name=Middelburg2019 />

The global ocean covers more than 70% of the Earth's surface and is remarkably heterogeneous. Marine productive areas, and coastal ecosystems comprise a minor fraction of the ocean in terms of surface area, yet have an enormous impact on global biogeochemical cycles carried out by microbial communities, which represent 90% of the ocean's biomass. Work in recent years has largely focused on cycling of carbon and macronutrients such as nitrogen, phosphorus, and silicate: other important elements such as sulfur or trace elements have been less studied, reflecting associated technical and logistical issues. Increasingly, these marine areas, and the taxa that form their ecosystems, are subject to significant anthropogenic pressure, impacting marine life and recycling of energy and nutrients.Galton, D. (1884) 10th Meeting: report of the royal commission on metropolitan sewage . J. Soc. Arts, 33: 290. A key example is that of cultural eutrophication, where agricultural runoff leads to nitrogen and phosphorus enrichment of coastal ecosystems, greatly increasing productivity resulting in algal blooms, deoxygenation of the water column and seabed, and increased greenhouse gas emissions, with direct local and global impacts on nitrogen and carbon cycles. However, the runoff of organic matter from the mainland to coastal ecosystems is just one of a series of pressing threats stressing microbial communities due to global change. Climate change has also resulted in changes in the cryosphere, as glaciers and permafrost melt, resulting in intensified marine stratification, while shifts of the redox-state in different biomes are rapidly reshaping microbial assemblages at an unprecedented rate. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

全球海洋覆盖了地球表面的70% 以上，而且非常不均匀。海洋生产区和沿海生态系统只占海洋表面积的一小部分，但却对微生物群落执行的全球生物地球化学循环产生巨大影响，微生物群落占海洋生物量的90% 。近年来的工作主要集中在碳和大量营养元素的循环，如氮、磷和硅酸盐: 其他重要元素，如硫和微量元素的研究较少，反映了相关的技术和后勤问题。这些海域以及形成其生态系统的分类群正日益受到人类活动的巨大压力，影响着海洋生物以及能量和营养物质的循环。高尔顿(1884)第十次会议: 皇家污水处理委员会报告。J. Soc.33:290.一个关键的例子是文化富营养化，农业径流导致沿海生态系统的氮和磷富集，大大提高生产力，造成藻类大量繁殖，水体和海床脱氧，温室气体排放增加，对氮和碳循环产生直接的地方和全球影响。然而，有机物从大陆流入沿海生态系统只是全球变化对微生物群落造成的一系列紧迫威胁之一。气候变化还导致冰冻圈的变化，冰川和永久冻土融化，加剧了海洋分层，而不同生物群中的氧化还原状态的变化正在以前所未有的速度迅速重塑微生物群落。50px 材料复制自这个来源，可以在知识共享署名4.0国际许可证下获得。

因此，全球变化影响着关键过程，包括初级生产力、 co2和 n2的固定、有机物呼吸/再矿化以及固定 co2的沉积和埋藏。此外，海洋正在经历酸化过程，从工业化前到今天，pH 值变化为0.1，影响碳酸盐/重碳酸盐缓冲化学。据报道，酸化反过来影响浮游生物群落，主要是通过对钙化类群的影响。还有证据表明，关键的中间挥发性产品的生产发生了变化，其中一些产品具有明显的温室效应(例如，由于全球温度升高、海洋分层和脱氧，在微生物过程驱动的所谓最低含氧区或缺氧海洋区，导致多达25% 至50% 的氮从海洋流失到大气中。其他产品，包括硫磺物种的减少，如 H2S，对海洋资源如渔业和沿海水产养殖产生负面影响。虽然全球变化加速，但人们对海洋生态系统的复杂性，特别是微生物作为生态系统运作的驱动者的根本作用的认识也同时提高。

The slow cycle is illustrated in the diagram above on the right. It involves medium to long-term [[geochemical]] processes belonging to the [[rock cycle]]. The exchange between the ocean and atmosphere can take centuries, and the [[weathering]] of rocks can take millions of years. Carbon in the ocean precipitates to the ocean floor where it can form [[sedimentary rock]] and be [[subducted]] into the [[earth's mantle]]. [[Mountain building]] processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by [[degassing]] and to the ocean by rivers. Other geologic carbon returns to the ocean through the [[Hydrothermal circulation|hydrothermal emission]] of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels.<ref name=Libes2015 /><ref name=Bush2020>{{cite book|doi = 10.1007/978-3-030-15424-0_3|url = https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|title = Climate Change and Renewable Energy|year = 2020|last1 = Bush|first1 = Martin J.|pages = 109–141|isbn = 978-3-030-15423-3|s2cid = 210305910|access-date = 2021-09-27|archive-date = 2021-09-27|archive-url = https://web.archive.org/web/20210927001642/https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|url-status = live}}</ref>

缓慢的循环在上面右边的图表中显示出来。它涉及中长期的地球化学过程，属于岩石旋回。海洋和大气之间的交换可能需要几个世纪，岩石的风化可能需要几百万年。海洋中的碳沉淀到海底，在那里它可以形成沉积岩并潜入地幔。造山过程导致这种地质碳返回到地球表面。在那里，岩石被风化，碳通过排气返回大气层，通过河流流入海洋。其他地质碳通过钙离子的水热释放返回海洋。在给定的一年中，1000万到1亿吨的碳在这个缓慢的循环周期中移动。这包括火山以二氧化碳的形式将地质碳直接返回大气层。然而，这还不到燃烧化石燃料排放到大气中的二氧化碳的百分之一。

The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 Pg of carbon and 2–19% of all biomass. Microorganisms drive organic and inorganic compound transformations in this environment and thereby control biogeochemical cycles. Current knowledge of the microbial ecology of the subsurface is primarily based on 16S ribosomal RNA (rRNA) gene sequences. Recent estimates show that <8% of 16S rRNA sequences in public databases derive from subsurface organisms and only a small fraction of those are represented by genomes or isolates. Thus, there is remarkably little reliable information about microbial metabolism in the subsurface. Further, little is known about how organisms in subsurface ecosystems are metabolically interconnected. Some cultivation-based studies of syntrophic consortia and small-scale metagenomic analyses of natural communities suggest that organisms are linked via metabolic handoffs: the transfer of redox reaction products of one organism to another. However, no complex environments have been dissected completely enough to resolve the metabolic interaction networks that underpin them. This restricts the ability of biogeochemical models to capture key aspects of the carbon and other nutrient cycles. New approaches such as genome-resolved metagenomics, an approach that can yield a comprehensive set of draft and even complete genomes for organisms without the requirement for laboratory isolation have the potential to provide this critical level of understanding of biogeochemical processes. 50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License .

陆地地下是地球上最大的碳储存库，含有14-135 Pg 的碳，占所有生物量的2-19% 。微生物在这种环境中推动有机和无机化合物的转变，从而控制生物地球化学循环。目前对地下微生物生态学的了解主要是基于16S 核糖体RNA 基因序列。最近的估计显示，公共数据库中的16s rRNA 序列中，少于8% 来自地下生物，其中只有一小部分由基因组或分离物表示。因此，关于地下微生物代谢的可靠信息非常少。此外，关于地下生态系统中的生物体是如何在新陈代谢上相互关联的，我们知之甚少。一些以培养为基础的联合营养研究和对自然群落的小规模宏基因组学分析表明，生物体之间是通过代谢传递联系起来的: 一种生物体的氧化还原反应产物转移到另一种生物体。然而，还没有一个复杂的环境被彻底剖析，足以解析支撑它们的代谢交互网络。这限制了生物地球化学模型捕捉碳和其他养分循环关键方面的能力。基因组分解宏基因组学等新的方法可以为生物体提供一套全面的草图甚至完整的基因组，而不需要实验室隔离，这种方法有可能提供对生物地球化学过程的这一关键水平的理解。50px 材料复制自这个来源，可以在知识共享署名4.0国际许可证下获得。
