水文过程中降雨径流对非点源污染的影响(英文)

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。

Influence of Rainfall Run-off in Hydrologic Process on Non-Point Pollution

Objective] This study aimed to study on influence of rainfall runoff on non-point pollution and to reduce the pollution through control 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 influence 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 controlling of non-point pollutants on the ground. Growing plants in slope effectively reduced the scour and erosion of rainfall runoff on soil. The study became simple thanks for the hydrological process. Conclusion] The research indicated that non-point pollution would be effectively reduced through control of rainfall runoff.
