摘要
城市雨水利用效益的定量识别和综合评价是一项前沿性研究工作,其结果可作为雨水利用工程的决策依据。系统分析了城市雨水利用效益评价指标体系,探索应用多层次半结构模糊决策法对雨水集蓄利用效益进行综合评价。以大连市瓦房店工业区雨水利用工程为例,对提出的3个雨水利用方案进行了综合效益评价和方案优选。结果表明,多层次半结构模糊决策法能较好地应用于城市雨水资源利用效益评价中。在雨水中水利用时,充分利用增渗设施和适当增加蓄水池容积可以提高雨水利用的综合效益。
It is an exploratory research to quantitatively identify and comprehensively assess the benefit of the urban rainwater utility（URU）,which can generate results helpful for decision making on the corresponding projects.Taken the rainwater utilization project in the Wafangdian industrial district as a case study,the index system of benefit assessment for URU was structured,the URU benefits were evaluated with a multi-level semi-constructive fuzzy optimization model,and an optimal scheme was then recommended.The results indicate that the multi-level semi-constructive fuzzy optimization model well met the needs of comprehensive benefit assessment of URU.The benefits of URU could be increased with enlarged reservoir volumes and/or infiltration enhancements.
