我国农村水环境非点源污染研究进展

农业非点源污染是导致水质污染最主要原因之一。我国农村非点源污染研究之初采用的研究方法主要有两种，一种是应用与水文模型紧密相关的模型来模拟和估算非点源污染负荷；另一种是通用土壤流失法。最近又提出了一种简便易用的流域非点源污染负荷估算方法－平均浓度法。将农业非点源污染负荷与3S技术结合、与水质模型对接用于流域水质管理成为农业非点源污染研究的新生长点。近年来，农村非点源污染研究也开始探索非点源污染负荷与河流水质模型接口问题。

Progress of Water Environmental Non-Point Source Pollution Study in Rural of China

Agriculture as non-point pollution source is the main factor which led to water pollution. At the beginning of non-point source pollution study, there are basically two study methods ,one is applying models related to hydrologic model to simulate and estimate non-point source pollution load ,another is common soil loss equation. A practical estimation method of non-point source pollution load-mean concentration method was established. Combining non-point source pollution load with 3S technology ,jointing with water quality model and applying them into water quality management became the new growth of non-point source pollution study .Recently, non-point source pollution study began to search the joint of non-point source pollution load and river water quality model.
