Research on Non-point Source Pollution in Taihu Lake Region

太湖流域非点源污染已经相当严重,直接威胁太湖流域的水环境安全.本文综述了太湖流域非点源污染来源于:农业生产的化肥、农药污染;畜禽水产养殖污染;城市地表径流面源和道路线源污染;城镇、农村生活污水的非达标排放;大气的干湿沉降等.并分析了太湖流域非点源污染的影响因素以及时空分布特点,最后从控制非点源污染源和污染物输移过程提出控制和治理非点源污染的措施.;With pollution from point sources being dramatically reduced, non-point source pollution(NPSP) is the major cause of most water that does not meet water quality goals. Based on the studies in recent years, this paper summarizes the research results of non-point source pollution in Taihu Region. Non-point source pollution is caused by soil erosion from cropland and from pesticide and fertilizer applications, livestock industry, urban runoff and village living sewage, and wet and dry deposition. The effect factors on NPSP are discussed and the distribution of NPSP in time and space is analyzed. At last, we propose several measurements to control and management NPSP.
