海绵城市建设效果评价方法研究

Study on Evaluation Method of Sponge City Construction Effect

为了定量评价海绵城市建设效果,通过采用层次集对分析法进行了海绵城市建设效果的评价研究。首先,根据海绵城市建设特点筛选出了海绵城市建设效果评价指标;然后,采用层次分析法确定各级评价指标的权重,利用集对分析法确定各级评价指标的联系度,并据此进行效果评价;最后,从水生态、水环境、水资源、水安全等多个角度对某城市的海绵城市建设效果进行综合分析评估与比较,并在此基础上提出改进措施和建设意见,指导海绵城市建设。

In order to quantitatively evaluate the construction effect of sponge city,the construction effect of sponge city is evaluated and studied by analytic hierarchy process and set pair analysis process.Firstly,according to the characteristics of sponge city construction,the evaluation indexes of sponge city construction effect are screened out.Then,the analytic hierarchy process is used to determine the weight of evaluation indexes at all levels,and the set pair analysis method is used to determine the connection degree of evaluation indexes at all levels.Accordingly,the effect evaluation is carried out.Finally,the construction effect of sponge city in a city is comprehensively analyzed,evaluated and compared from the perspectives of water ecology,water environment,water resources and water security.On this basis,the improvement measures and construction opinions are put forward to guide the construction of sponge city.
