摘要
地表水体富营养化是水污染的核心问题之一,而预防和降低磷养分流失是控制水体富营养化的关键途径。农业非点源污染因为具有时空范围广,不确定性大,污染严重的特点,已成为影响水环境的重要污染源,其中氮、磷的农业非点源污染又是最主要的。在分析农业非点源污染的研究现状和特点的基础上,结合其成因和影响因素,提出了相应的防治对策。
Eutrophication is one of key water pollution issues, and phosphorus （P） is considered as the critical control factor. Agricultural non - point sources pollution has the characteristics of wide spatial temporal range, great uncertainly and serious pollution. It has been the key pollution source of water environmental quality, Where nitrogen, phosphorus in agricul- tural non - point sources pollution is the most important factor. Based on current status and characteristics of agricultural non - point source pollution, with its causes and influence of factors. The prevention and cure countermeasures to control agricultural non- point source pollution were put forward in this paper.
