水土保持的水环境质量效应研究进展

 随着点源污染逐步得到有效的控制,非点源污染对经济社会可持续发展的危害更加突显。根据水土流失与非点源污染的联动关系,界定了水土保持水环境质量效应的概念;将国内外与水土保持和水土流失有关的非点源污染研究归纳为3个方面:污染物运移的影响因子与机制分析、非点源污染模型的研发和非点源污染控制措施研究。对其研究进展分别进行了介绍和评述,并展望了发展趋势。

Advances in water environment quality effects of soil and water conservation

With point source pollution gradually being controlled,the harm of nonpoint source pollution to(economic) and social sustainable development are becoming more and more serious.Because of the close relationship between soil erosion and nonpoint source pollution,it is absolutely necessary and imperative to intensify the research on soil and water conservation controlling nonpoint source pollution. The concept of water(environment) quality effects of soil and water conservation was put forward for the first time;External and(domestic) researched findings related with soil and water conservation and soil erosion on nonpoint source pollution were summed up into three respects: analyses of affecting factors of pollutants movement and mechanism,research and development of models of nonpoint source pollution,research of controlling measures of nonpoint source pollution.Their researching progresses were introduced and reviewed,and their developing tendency was analyzed.
