1.In this paper, these pollution produced by soil and water loss is defined as nonpoint pollution of soil and water loss type (NPSWLT).
2.Endogenous effect mechanism of rural nonpoint pollution control are lack both in domestic and abroad.
3.Storm drainage, even though the water may enter watercourses by way of pipes or channels, is considered nonpoint source pollution.
4.The nonpoint source pollution, which has played an important role on surface water pollution has been given much attention because of the effective controlling of the point source pollution.
5.And among all sorts of nonpoint source pollutions, agricultural nonpoint source pollution is the biggest one.
6.Water pollutants are categorized as point source or nonpoint source, the former being identified as all dry weather pollutants that enter watercourses through pipes or channels.
7.The research results indicated: soil and water conservation measures are important means to control nonpoint source contamination, protect water source quality and ensure drinking water security.
