摘　　要：随着城市的迅速发展,城市面源污染日益成为影响城市水体水质的重要因素。本文按照地表累积—降水—径流冲刷—输送这一城市面源污染的形成过程对次降雨径流平均浓度、初始冲刷效益等污染特征进行了研究,分析了不同下垫面及不同功能区的污染特性。With the rapid development, the nonpoint pollution in urban area becomes an important factor affecting the urban water quality more and more. In this paper, along with the process of urban nonpoint pollution formation, namely accumulation on surface-rainfall-runoff washing-drainage, the pollution characteristics such as event mean concentration （EMC） and first flush effects （FFE） were studied, meanwhile the pollution features for different underlying surface and functional area were analyzed as well.
