It is a critical basis for utilization of rainfall resource and pollution control of runoff in urban area to understand runoff quality and its main influential factors.On the basis of large quality data selected from rainfall events during 1998-2000 in Beijing , this article analyzes the quality of runoff from roofs and roads, and major factors which affect the quality. The quality of the runoff is very poor, the polluting strength of the first flash of the runoff is higher that of raw sewage. In addition to air quality, the most important influential factors are roof material, road type and its pollution condition, air temperature, rainfall intensity and volume, and interval of rainfall events etc. Some necessary management measurements for utilization and pollution control of the urban runoff in Beijing are discussed.

掌握城区雨水径流水质及其主要的影响因素是有效地利用城区雨水资源和控制城市非点源污染的基础。根据北京 1998— 2 0 0 0年大量的降雨径流水质数据 ,本文分析了城区屋面和道路雨水径流的水质变化规律及其主要影响因素城市雨水径流的水质很差 ,初期径流的污染程度甚至超过城市污水。除了空气质量的影响外 ,最重要的影响因素是屋面材料、道路类型及路面污染状况、气温、降雨强度、降雨量和降雨间隔时间等
