• 摘要：本文将降雨—径流—地表冲刷—受纳水体水质状况概念化为一个系统进行研究。进行了自街道固形物推算径流污染物总量方法的实践,提出了点源、非点源污染分别计算然后线性叠加的近似方法。 结合北京城区实测资料,对北京市城市径流污染状况予以评价,并给出定量判断的方法和结论,认为北京市径流污染量目前只占点污染源的3—5%。 文章是跨环境、水利、市政三学科进行城市化问题研究的尝试。

• Abstract：The article is to try to make precipitation-runoff-surface sweeping-quality of receiving waters being organized into a single system After the practical method of deriving total amount of runoff pollutants from solids in street, it is possible to present this approximate method of lineariterated addition after calculating point and non-point pollution source respectively.Based on practical information for city proper of Beijing, the author assesses the municipal runoff pollution situation, and gives out method and conclusion on a quantitative judgement. It is considered that only 3-5% of point pollution contributes municipal runoff pollution.It has been attempted to attack this problem of urbanization with a multidisciplinary idea including environment, water conservancy and municipal administration.
