摘要[目的]研究降雨径流对非点源污染的影响,拟通过控制降雨径流产生的污染来减少非点源污染。[方法]通过分析降雨径流的
水文过程、其与非点源污染物的作用机理及其对非点源污染的影响,以及水文模型在该研究中的应用,探讨如何有效的减少非点源污
染。[结果]降雨径流是非点源污染的主要原因,通过源头控制,加强地表非点源污染物清除和控制,在坡地上种植植被,可有效减少降
雨径流对土地的冲刷和侵蚀,减少水土流失。水文模型的应用使该研究简单化。[结论]研究表明对降雨径流过程进行控制将有效减少
非点源污染。

Abstract [Objective] This study aimed to study on influence of rainfall runoff on non-point pollution and to reduce the pollution through con-
trol of the contamination produced from rainfall runoff. [Method] In order to explore effective methods to decrease non-point pollution,we
conducted analysis on hydrological process of rainfall runoff,interaction mechanism between the process and non-point pollutants,the influ-
ence on non-point pollution and hydrological model application in the research. [Result] It was proved that rainfall runoff was the main factor
of non-point pollution. Control from source strengthened clearing and contr
