以郑州市河网水系为例，研究对比了生态治理前、后的河网水系格局与连通性。采用基于图论的连通性评价法，将郑州市河网水系概化为图模型，对生态规划前后的水系连通性进行评价，并计算了边连通度；同时选取了部分数量特征和结构特征指标进行水系格局评价。通过对比得出结论：生态治理后郑州市河网水系的连通性和连通度都有了很大提高，水系格局的指标也有大幅度增长，河网由不连通变连通，河网稳定性增强。

Selecting the river water system of the Zhengzhou City as study site,this paper compared drainage pattern and connectivity change of the river network before and after the ecological planning. The connectivity evaluation method was adopted based on graph theory. The river water system was simplified to a graph model,evaluated the water system connectivity after the ecological planning,and calculated the edge- connectivity. It selected a part of quantitative features and structural features which were on behalf of the drainage pattern characteristics to evaluate the drainage pattern. By contrasting,it is concluded that the connectivity of river water system has been greatly improved after the ecological planning. The results of the drainage pattern indicate in a marked rise,and the river network becomes connected. Moreover,the connectivity of river network stability is enhanced.
