我国农业面源污染治理技术研究进展

农业面源污染逐渐成为制约我国现代农业和经济社会可持续发展的重大障碍,其治理工作在我国生态环境保护与治理工作中的重要性日益加强。本文概述了农业面源污染的基本概念、特征与成因,根据农业面源污染的"产-流-汇"3个发生发展阶段,总结了现阶段农业面源氮磷污染的治理理论与技术,并根据各阶段治理技术的优缺点提出我国未来农业面源污染治理过程中应该加强污染产生机制和迁移转化过程的研究,同时,通过少量的人工干预,努力提高单项治理技术的治理效率,将农业面源污染发生与发展的"产-流-汇"3个阶段的治理技术结合起来,突出流域治理思路。

Review of Agricultural Non-point Source Pollution Control Technology

Agricultural non-point source pollution has become a significant barrier for the sustainable development of modern agriculture and economic society in China.The treatment has become increasing crucial in the ecological environment protection work in China.This article overviewed the basic concepts,characteristics and causes of agricultural non-point source pollution,and summarized control theory and techniques of agricultural non-point source nitrogen and phosphorus pollution.Based on the advantages and disadvantages of the treatment technologies in various stages of agricultural non-point sources pollution,this article also proposed that the research on the pollution generation mechanism,migration and transformation processes of agricultural non-point source pollution should be strengthened,and the efficiency of the individual treatment technology should be improved through some manual intervention.Finally,combined with the agricultural non-point source pollution causes and deterioration with the ＂production-flow-sink＂three-stage of treatment technology,the river basin treatment thinking can be highlighted.
