摘　　要：在科技发展的现代社会,非点源污染已经成为造成各个水域污染的主要原因,特别是多雨城市,非点源污染尤为严重。为了尽量预防对于水资源的污染,需要实施风险评价,因此提出多雨城市排水环境非点源潜在污染风险评价方法。该方法首先对武汉地区各排水环境的样品实施采集,之后根据现有的风险评价指标对排水环境风险实施分级,最后构建评价模型对排水环境的非点源潜在污染风险实施评价。该方法很好的改进了传统方法不考虑降水因子影响的弊端,更具有实用性。With the development of science and technology,non point source pollution has become the main cause of water pollution,especially in rainy cities,where non point source pollution is particularly serious.In order to prevent the pollution of water resources as much as possible,it is necessary to conduct risk assessment on them.Therefore,a method for assessing the potential pollution risk of non point sources in the drainage environment of rainy cities is proposed.This method first collects samples from various drainage environments in Wuhan,then grades the risks of the drainage environment according to existing risk assessment indicators.It finally constructs an evaluation model to evaluate the potential pollution risks of non point sources in the drainage environment.This method greatly improves the disadvantage of traditional methods that do not consider the impact of precipitation factors,and is more practical.
