摘要
随着农业投入的加大,农业非点源污染造成的影响逐渐凸显,环境压力越来越大。国内外农业非点源污染现状已引起高度关注,各国学者已经从非点源污染物污染特征、类型、污染负荷输出模型模拟等不同方面进行了系统地探索和研究。国外农业非点源污染研究起步于20世纪60年代,中国的非点源污染相关研究起步较晚,仍局限于狭义的非点源污染的研究。本文重点介绍了国内外目前的污染现状和农业非点源污染模型的研究进展,分析了非点源污染形成的原因,并在此基础上讨论了目前研究中存在的问题和未来的发展方向。
Along with the increase of agricultural investment,the influence caused by ANPS is gradually serious,and so is environment stress.Domestic and overseas ANPS are paid more attention.The characters,types,and models of ANPS have been explored and studied by many researchers.Researches of overseas ANPS were from 60's last century,while domestic ANPS researches were late than the former,which were limited to the researches in narrow sense.The article mainly introduced the status analysis of domestic and overseas ANPS and the advances in ANPS models,analyzed the reason that ANPS formed and discussed the exiting problems in current research and development in the future.
