摘要
水文系统由多个子系统组成,并受到多要素、多尺度的共同作用,导致它们在时空上产生多种复杂形式的关联结构,形成了一个巨大的复杂系统。因此,利用复杂网络理论研究水文问题也引起学者的注意。首先分析了水文系统的复杂性,介绍了复杂网络的相关知识,然后综述了其在水文研究中的应用,包括利用复杂网络统计性质分析水文过程;利用复杂网络社团挖掘算法进行流域划分;利用节点重要性评估优化水文监测网络。最后展望了利用复杂网络解决水文中其它问题新的方向。
The hydrological system is composed by subsystems,and affected by the interaction of multi factors,multi scale,which result in interaction structure of more complex produced in time and space and formed a great complex system. So it has also caused more attention by scholars to use complex network theory to study hydrological problem of. This paper first analyzed the complexity of hydrological system,and introduced the related knowledge of complex network. Then it summarized some applications in hydrological research which included analysing hydrological process by using the statistical properties of complex networks; realizing watershed delineation by using complex network ＇s community mining algorithm; optimizing hydrological monitoring network by using the evaluation of node＇s importance. Finally,the paper prospected the new direction to resolve other problems in hydrological system with complex networks.
