Urban non-point pollution is a new issue appeared with rapid urbanization, which mainly comes from city industrial emission, fossil fuel burning, vehicle exhaust, and soil erosion, etc., and seriously endangers the safety of urban water quality and ecosystem through the flush of storm runoff into urban waters. This paper elucidated the connotations of urban non point pollution, its formation process, and affecting factors, introduced the research methods of urban storm runoff, including event mean concentration (EMC) and first flush (FF), and the research progress of two non-point source pollution models (SWMM and HSPF), and summarized the applications of best management practices (BMPs) and low impact development (LID) in controlling urban non-point pollution. In view of the shortages of current related studies, it was proposed that on the basis of strengthening the researches of pollutant movement …
