雨水排水也会通过水管或管道进入水道，这都被认为是非点源污染。

In this paper, these pollution produced by soil and water loss is defined as nonpoint pollution of soil and water loss type (NPSWLT).

本文定义这种污染方式这种为水土流失型非源污染。

Other nonpoint source pollution comes from agricultural runoff, construction sites, and other land disturbances, as discussed in Chap. 11.

The definitions of urban nonpoint source pollution were summarized, and the categories, sources, hazards and factors of urban nonpoint source pollution were discussed.

总结了城市非点源污染的定义，探讨了城市非点源污染的种类、来源、危害、影响因素等特征。

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.

水污染物分为点源和非点源，前者认为所有干燥空气污染物通过水管或管道进入水道。

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.

在点源污染逐步得到有效控制的今天，面源，这一对地表水体水质有严重影响的污染源在发达国家已经引起了极大的关注。
