摘　　要：我国水资源短缺,许多城市都面临着水资源短缺问题。充分利用城市降水资源,实施雨水资源化是一条既经济快捷又广泛有效的途径,并可带来一系列生态环境效应。根据城市下垫面性质的不同,将城市建成区划分为不透水区、园林绿地区和水域区3种类型,分别分析了在这3种下垫面情况下雨水资源的利用方式和利用潜力,提出了城市雨水资源化潜力模型。最后利用逐日降水资料,分析了商丘市2000-2005年城市雨水资源化现实潜力。计算结果表明,商丘市年平均雨水资源化可能潜力为22.94×106m3,现实潜力为18.58×106m3,接近常年城市供水总量的30%。China is one of the countries in serious shortage of water resources and water shortage has been a serious problem confronted by many cities.Rainwater is one of the most essential,direct and economical resources that could be utilized.The utilization of urban rainwater resources can solve the problem of urban water resources crisis and bring a series of good eco-environmental effects.City underlining surface can be divided into three types such as the staunch surface,the greenbelt and the water surface.The rainwater resources utilizing methods and potential in different underling surfaces are analyzed,and the potential model of urban rainwater resources is set up.At last,based on the daily rain data of Shangqiu from 2000 to 2005,the city rainwater resources are calculated.Results show that the potential resources of Shangqiu rainwater can be 22.94×106 m3 and the practical resources can be 18.58×106 m3,which is about 30 percent of the urban water supply.
