基于点-面两层结构的复杂网络方法评估海河流域水网连通性
Evaluation of water network connectivity using complex network method based on node-subbasin double layer structure
摘要
Abstract
The connectivity of the river and lake system is a new concept of water treatment proposed in the new era.According to the concept,the rivers and lakes can be connected by constructing new canals and channels,also by the transformation of lakes,by which differnt rivers and lakes become an intercon-nected water network system.Based on the complex network method,the connectivity of the water net-work of the Haihe River Basin was analyzed from the two levels of the node and the subbasin.At the sub-basin level,the connectivity of the basin was evaluated by the average index,and the overall water sys-tem connectivity of the basin was analyzed using the network diameter,average path length,etc.as sup-plementary indicators.At the level of a single node,the connectivity of each node in the basin was ana-lyzed using degree index and betweeness centrality index.Therefore,the water system connectivity was analyzed from both node and subbasin levels,which realized the combination of microscopic and macro-scopic perspectives.In addition,the clustering coefficent was also introduced for a better understanding of the spatial distribution characteristics of the river network in each subbasin.According to the rationality assessment of the results,it can be seen that the complex network method is conducive to the analysis of the characteristics and connectivity of the water system in the basin,and this method has excellent appli-cation prospects.关键词
