摘要
随着点源污染的逐步有效整治及化肥农药的大量施用,农业非点源污染已经成为河湖、水库等水体污染的主要来源。本文在分析农业非点源污染成因的基础上,归纳了当前农业非点源污染的常用模型及与GIS的结合应用技术,并从不同角度提出了切实有效的农业非点源污染防控措施;基于当前研究进展,提出"3S"技术、以基因工程为主导的生物技术以及将科学技术与BMPs相结合等将是未来农业非点源污染研究的重点。
With the gradual effective renovation of point source pollution and excessive use of pesticides and tertilizers, the agricultural non-point source pollution has become a major source pollution of rivers,lakes, reservoirs and other waters.According to the analysis of causes from agricultural non-point source pollution,the main models of agricultural non-point source pollution were listed, and the application technology of combination of GIS and models was summed up.Meanwhile,the effective prevention and control measures of agricultural non-point source pollution were proposed practically from different angles.Finally, based on the current research progress, the points that the development of “3S” technology ,the biotechnology dominated by genetic engineering and the combination of science technology and BMPs would be the focus of agricultural non-point source pollution research in the future were put forward.
