农业非点源污染研究方法分析

非点源污染受到人们越来越多的重视,尤以农业非点源污染为重。该文在对农业非点源污染的来源、特征介绍的基础上,对国内外农业非点源污染负荷模拟模型进行了梳理,根据国内学者对入河系数、农田种植、畜禽养殖和农村生活等方面的研究做了概述,并在流域监测、3S技术、污染源区识别以及多领域结合等方面对整个农业非点源污染负荷的研究进行了建议和展望,最后对该文所述进行了总结。

Study on Methods of Agricultural Non-point Source Pollution

The non-point source pollution had attracted more attention, especially for agricultural NPS. This article dis-cussed NPS models at home and abroad on the basis of introduction of sources and characteristics of agriculture NPS. Overviews were showed according to studies of export coefficient,agricultural cultivation,livestock breeding and rural lives from researchers inland. Suggestions and prospects had been brought up for valley monitoring,3S technology,discernment on pollution source area and multidisciplinary combination for studies on the whole agricultural NPS load.
