考虑水力连通性的水系连通评价指标体系构建与应用EI北大核心CSCD

在水系形态特征与水系结构连通性基础上,增加了包含水工建筑物数量、下游收水量和换水周期在内的水力连通性评价指标,构建了更加全面的水系连通评价指标体系。通过层次分析与熵权法相结合的综合评价法确定各指标权重,并利用该评价指标体系对廊坊市北运河-永定河区域水网3种水系连通方案进行了评价,得到最优水系连通方案。评价结果表明,构建的评价指标体系能够更加全面地表征水系连通情况,可用于河网水系连通评价。

Construction and application of water system connectivity evaluation index system considering hydraulic connectivity

Based on the morphological characteristics of water system and the connectivity of water system structure, with the addition of hydraulic connectivity evaluation indexes including the number of hydraulic buildings, downstream water intake and water exchange period, a more comprehensive evaluation index system of water system connectivity was constructed. The weight of each index was determined by the comprehensive evaluation method combining analytic hierarchy process and entropy weight method. The evaluation index system was used to evaluate three water system connectivity schemes of the North Canal and Yongding River regional water network in Langfang City, and the optimal water system connectivity scheme was obtained. The evaluation results show that the constructed evaluation index system can represent the water system connectivity more comprehensively, and the results can provide reference for the water system connectivity evaluation in the river network.
