摘　　要：成都降水呈现极强的季节性特征,夏季降水占全年降水的50%左右;降雨水质呈现明显偏硝酸的混合酸性。针对成都地区雨水污染物特征,对当前雨水处理及回用工程中的中水工程、屋顶绿化、调蓄池、绿地系统以及湿地系统在成都应用时所应注意的一些关键因素进行了讨论。The precipitation in Chengdu distributes seasonally very much. Especially the precipitation in summer accounts for about 50% of the annual amount. Moreover, the rainwater quality presents mixed acidity with nitric acid as dominance. Based on the analysis of the characteristics of rainwater pollutants in Chengdu, some key points that should be noted in projects concerning re-claimed water reusing system, roof greening, pondage reservoir, greenbelt and constructed wetland system were discussed.
