摘要
水土流失既是一种非点源污染形式,同时又是其它非点源污染物流失的载体。其它非点源污染物通过流失的土壤颗粒的携带作用进入水体,造成水体污染。水土流失是引起农业非点源污染的一个重要原因,控制水土流失是减少农业非点源污染的必要途径。
The water ＆ soil loss not only is a non- point source pollution, but also is a carder on else non- point source pollutants. The soil particles taking a lot of non - point source pollutants when they came into water environment. Water ＆ soil loss is the important reason that leading to the agriculture non - point source pollution. Controlling the water ＆ soil loss occurrence is the essential pass for reducing the agriculture non - point source pollution.
