摘　　要：南方地区降雨和地形特征会对合流制排水系统产生较大压力而带来更频繁的溢流,污染受纳水体。通过实测数据分析区域降雨-溢流关系,考察溢流水量、水质变化,随后进一步分析内河与外江水质受降雨和溢流的影响规律,总结区域降雨、溢流及水质特征,结合工程案例,提出南方城市雨期河流水质控制建议。In southern China,rainfall and topographic characteristics posed greater pressure on the combined drainage system,resulting in more frequent combined sewer overflow,which causes pollution to receiving water bodies.Based on the measured data,the relation between rainfall and overflow in the region was analyzed,and the changes of overflow quantity and water quality were investigated.Then the influence of rainfall and combined sewer overflow on water quality of inland and outer rivers was further analyzed.Finally,the characteristics of regional rainfall,overflow and water quality were summarized,and the suggestions of river water quality control in southern cities during rainy season were proposed.
