摘要
近年来,太湖流域农业面源污染占流域污染负荷的比例逐步提高,已经成为太湖流域水污染物的主要来源。阐述了流域农业面源污染的概况,从种植业、畜禽养殖业、农村生活和水产养殖4个方面分析流域农业面源污染的构成。其中,种植业污染主要是由化肥、农药和农膜的过度使用引起。接着从政策、经济和技术3个层面详细探讨了农业面源污染产生的内在机理,并在此基础上提出相应的防控措施建议。
In recent years, the proportion of agricuhural non-point source pollution in Taihu Lake and Taihu Basin has gradually increased. It has becomes the main source of water pollutants in Taihu River and Basin. This paper briefly introduces the general situation of agricultural non-point source pollution, and the causes from four aspects, including planting, livestock and poultry breeding, rural living and aquaculture. Among them, the planting industry pollution is mainly due to the excessive use of chemical fertihzer, pesticide and agricultural film. Then, the inherent formation mechanism of agricultural non-point source pollution was explored separately from the three levels of policy, economy and technology. On this basis, measures for the pollution prevention and control were finally suggested.
