【摘要】 城市地表径流是城市内河水体的主要污染源.以福州市典型内河—晋安河为代表,在内河沿线选取不同功能区,通过对不同功能区地表径流样品的采集与分析,来了解地表径流中主要污染物的变化规律及这些污染物对内河污染的作用程度.结果表明,不同功能区径流中的污染物以TN的污染贡献为最大;地表径流中的重金属物质不是内河水体污染的主要贡献者;停车场、道路是向内河输入污染物的主要功能区,城市绿地及住宅小区次之.更多还原

【Abstract】 Urban runoff is one of the major pollution sources to internal rivers.This paper,selecting Jin An River typical internal river in Fuzhou as a case study,we collects and analyzes runoff samples from different functional areas along the river to learn the changes of the major pollutants in surface water of these areas and their contribution to the internal river pollution.The result showed that,TN is ranked the top of all the pollutants;heavy metals in runoff has no impact to internal water pollution;parking lots and roads contribute the most to internal river pollution among all the functional areas,followed by urban green lands and residential communities.更多还原
