农业面源污染特征及治理对策

Research and Management of Agricultural Non-point Source Pollution

随着社会经济的发展,中国农业面源污染日益严重,面源污染在很大程度上引起耕地退化,严重影响农产品的质与量。在概述农村面源污染特征的基础上,分析农村面源污染的影响因素,其中化学肥料、农药、畜禽粪便及养殖废弃物、生产和生活污水、生活垃圾等是面源污染的重要因子,从农作技术、水土保持及意识政策等多方面考虑提出农业面源污染的防治措施,并对中国农业面源污染的未来研究进行展望。

With the development of social economy,the agricultural non-point source pollution is increasingly serious in our country,non-point source pollution to a great extent,cause land degradation,serious impact on the quantity and quality of the agricultural products. Based on the summarization of the agricultural non-point source pollution＇s characteristics,analyze the influence factors of the agricultural non-point source pollution of chemical fertilizers,pesticides,and breeding of animal manure waste,production and life sewage,life rubbish and so on is an important factor of non-point source pollution. Finally,from the consciousness of farming technology,water and soil conservation,and policy aspects of consideration of agricultural non-point source pollution prevention and control measures are put forward and the future research of agricultural non-point source pollution in our country were discussed.
