植被过滤带阻控除草剂污染的研究与应用进展

Research and Application Advances on the Control of Pesticide Pollution with a Vegetative Filter Strip

除草剂等农药在农业生产上作出了极大的贡献,但未被利用的农药因雨水和灌溉随地表径流进入水体,破坏了水生态系统,对人类健康构成威胁。本文对植被过滤带阻控除草剂污染的作用进行了阐述,综述了植被过滤带阻控除草剂污染的机理及影响其功能的主要因素,指出目前研究的局限和应用中应该考虑的问题,并对下一步研究方向进行展望。

Pesticides play an important role in agriculture. However,most of the applied pesticide easily flow into the aquatic environment through surface runoff caused by rain or irrigation. The entry of a pesticide into water may damage the aquatic ecosystem and constitute a potential risk to human health. This paper elaborates on the effect of a vegetative filter strip（VFS） on herbicide pollution control,analyzes the related mechanisms,and summarizes the factors influencing the function of VFS. Opinions and suggestions are provided regarding application. Gaps inresearch on the control of pesticide pollution via VFS are addressed.
