摘要
西苕溪是太湖重要的来水支流,非点源污染是导致西苕溪水质恶化的主要因素,鉴于对防治太湖富营养化和水华等环境问题的关注,近年来有不少对太湖水源区非点源污染的研究.本文从非点源污染源调查、污染负荷估算与模拟、污染的影响因素与机理等方面初步梳理了近年来西苕溪流域非点源污染的研究进展.明确了西苕溪流域非点源污染的一些基本特征,如污染物主要来自于水土流失、化肥施用等,其负荷量受年降雨、土地利用变化等因素影响较大.并对这里非点源污染接下来的研究提出了一些建议.
West tiaoxi river is an important tributary of Taihu lake and the most pollutants inflowing the river are from non-point source pollution.This paper reviews plenty of recent researches on non-point source pollution in the watershed from the pollution source surveys to pollution load estimates and simulations and summarizes the factors and mechanisms of pollution.Non-point source pollution mainly comes from soil erosion,irrational chemicals utilization and so on,and pollution loads vary with rainfall and land use.Finally,this article proposes some advices on non-point source pollution research in the future.
