城市雨水利用系统的模糊层次综合评价

Overall evaluation of urban rainwater utilization system by fuzzy-analytic hierarchy process

为明确城市雨水利用系统的综合效益,以促进其在居住小区的推广应用,采用模糊层次分析法(F-AHP)建立了一种简单的雨水利用系统综合评价模型,分别对雨水收集回用和雨水下渗两种方案进行评价。结果表明,前者经济效益和社会效益均较好,后者环境效益显著。该模型为促进城市雨水利用系统的建设提供了科学依据。

In order to know the comprehensive benefits of urban rainwater utilization system and promote the application of it in residential quarters, a simple model for the overall evaluation of rainwater utilization system was established using fuzzy-analytic hierarchy process （F-AHP）, two schemes： rainwater collection and reuse and rainwater infiltration were evaluated respectively. The results showed that, the former had better economic and social benefits; however, the latter could achieve remarkable environmental benefit. The said model provided a scientific basis for the construction of urban rainwater utilization systems construction.
