农业非点源污染研究动态及发展趋势
首发时间:2010-02-01
摘要:随着农业非点源污染和水污染问题的日趋严重,农业非点源污染研究逐渐引起高度重视。本文从理论研究、模型研究及防治技术研究等几个方面对当前国内外农业非点源污染的研究动态进行了回顾和总结,分析了我国农业非点源污染研究中存在的主要问题,并对农业非点源污染研究的发展趋势进行了展望。针对该研究的不足,指出了未来农业非点源污染研究的方向:多学科联合、进一步加强污染物迁移转化规律研究以完善理论研究体系,充分利用“3S”集成技术、加强非点源污染模拟的不确定性研究以构建实用性模型,并从工程措施和管理措施两个方面加强污染防治技术研究。

The Research Development and Prospect of Agricultural Non-point Source Pollution
Abstract:With the more and more deterioration of the agricultural non-point source pollution and the situation of water pollution, the researches on agricultural non-point source pollution have caused much attention. The research development on agricultural non-point source pollution at home and abroad is reviewed and summarized from aspects of theoretic researches, modeling methodologies and control techniques in this paper. Through analyses of the main problems exiting in the study of agricultural non-point source pollution in China, the countermeasure and the research directions of non-point source pollution in the near future are put forward as: improvement of theoretical systems through combining multi-discipline and intensifying laws research of non-point source pollution migration, construction of practical models through integrating “3S” techniques and uncertainty study of simulation, and strengthening the control technique study from perspectives of technique and management.
Keywords: agriculture non-point source pollution research development problem existing countermeasure
