　　在研究国内外有关雨水径流非点源污染研究成果的基础上，综述了城市道路、屋面、绿地雨水的水质特征及其影响因素，初期冲刷情况，以及初期雨水径流的截流控制应对方法。降雨的初期径流普遍有较高的污染物浓度，COD、T SS、T N、T P浓度值与城市污水浓度相近，截流处理这部分流量对保护水体环境意义重大。

Based on the research of non-point source pollution caused by urban runoff at home and abroad ,a summa-ry was made on runoff quality characteristics ,their influencing factors ,first flush situation and the flow control of initial rainwater runoff of city roads ,roofs and green lands .Generally ,initial rainwater runoff has higher concentra-tion of pollutants ,while its concentration values of COD ,TSS ,TN and TP are similar to that of urban sewerage . It’s of great significance for water environment protection to handle this part of the flow .
