摘要
农田氮、磷的流失,不仅造成化肥利用率的降低,还会引起农业非点源污染。通过分析国内外由于农田氮磷流失而引起的农业非点源污染现状和流失途径,提出加强污染源监控预警,综合运用管理措施和生态工程等,控制和减少农田氮磷流失对水体环境的污染。
The loss of nitrogen and phosphorus lead to not only the decrease of utilization of fertilizer,but also the agricural non-point source pollution.Through the analysis of nitrogen and phosphorus at home and abroad due to the loss of farmland caused by agricultural non-point source pollution status and the loss of channels.The author put forward to strengthen early warning pollution monitoring and use measures and ecological projects synthetically to control and reduce the pollution to the water body due to the loss nitrogen and phosphor of farmland.
