基于水资源配置网络图的水系连通评价体系研究——以廊坊市为例

在城市化背景下,人类生产生活的取排水对河湖水系格局产生了巨大的影响。在自然水系连通格局的基础上,从二元水循环水资源配置网络图出发,结合生产生活用水水平评价指标以及自然水系连通形态指标,构建一套可用于描述在不同时间节点下的调水工程对自然—人工二元结合水系连通度影响的综合评价指标体系,以廊坊市进行实证分析,最终指标评价等级与现状调查及未来规划所评价结果基本一致,说明构建的综合评价指标体系具有可靠性和有效性。

Research on the Evaluation System of Water System Connectivity Based on the Network Diagram of Water Resources Allocation:Taking Langfang City as an Example

In the context of urbanization,the intake and drainage of human production and life have a huge impact on the pattern of rivers and lakes.On the basis of the connected pattern of natural water system,a comprehensive evaluation index system can be used to describe the influence of water transfer project on natural-artificial binary water system connectivity under different time nodes based on the network diagram of water resource allocation in the binary water cycle,combined with the evaluation index of production and living water level and the connected form the index of natural water system.By taking Langfang City as an example,the results show that the evaluation grade of the final index is consistent with the current situation survey and future planning.It shows that the comprehensive evaluation index system established in this paper is reliable and effective.
