A '''spatial network''' (sometimes also '''[[Geometric graph theory|geometric graph]]''') is a [[Graph (discrete mathematics)|graph]] in which the [[Vertex (graph theory)|vertices]] or [[Edge (graph theory)|edges]] are ''spatial elements'' associated with [[Geometry|geometric]] objects, i.e., the nodes are located in a space equipped with a certain [[Metric (mathematics)|metric]].<ref name="Bart">{{cite journal | last1 = Barthelemy | first1 = M. | year = 2011| title = Spatial Networks | arxiv = 1010.0302 | journal = Physics Reports | volume = 499 | issue = 1–3 | pages = 1–101 | doi=10.1016/j.physrep.2010.11.002 | bibcode = 2011PhR...499....1B| s2cid = 4627021 }}</ref><ref name="Bart2">M.

'''空间网络 spatial network'''（也被称为'''[[几何图]] geometric graph'''）是一种图，其中顶点或边是与几何对象关联的空间元素，例如节点位于有特定度量的空间中，具有空间位置信息。<ref name="Bart" /><ref name="Bart2" /> 空间网络最简单的数学形式是[[晶格]]或[[随机几何图]]（见右图），其中节点随机均匀分布在二维平面上；如果一对节点之间[[欧氏距离]]小于给定的邻域半径，则将该对节点相连。[[交通和移动网络]]、[[互联网]]、[[移动电话网络]]、[[电网]]、[[社交网络]]以及[[生物神经网络]]都是图具有空间相关性的示例，并且这些图的拓扑性质本身并不包含关于网络的所有信息。表征和理解空间网络的结构、适应力和演化过程对于如城市化、流行病学等的不同领域都至关重要。
