农业非点源污染的环境影响及防治对策

Water Environmental Pollution Caused by Agricultural Non-Point Sources and Prevention Measures

非点源污染负荷在水环境污染中所占比例日益增大,而农业生产活动又是最大的非点源污染。由于没有固定的污染源,控制非点源污染要比控制点源污染困难得多。扼要介绍了我国农业非点源污染的现状,分析了农业非点源污染的各种影响因素,讨论了农业非点源污染对水环境的影响,并针对目前农业非点源污染存在的问题,提出了污染防治对策和管理措施。

The proportion of non-point sources in water environmental pollution was greater than before, and farming activity was the most important factor in agricultural non-point sources. Because of not having a fixed point sources, it was difficult to control non-point sources. Based on the harms of agricultural non point sources, this paper summarized the existing condition of non-point sources in China, analyzed its affecting factord, discussed water environmental deterioration impacted by farming activities, and put forward countermeasures of control and management.
