摘要
近年来，由于点源污染治理成果显著，非点源污染得到了人们的极大关注。剖析土地利用方式与污染负荷之间的内在联系是国外非点源污染研究的基本出发点，在此基础上产生了许多非点源污染负荷模型．SWAT模型嘞就是其中一例。介绍了SWAT的模型机理及国内外对SWAT的研究成果。在此基础上。对其在国内的应用前景进行了系统的展望。
In recent years, because point source pollution has been treated well, non-point source pollution has attracted more attentions. Over the world, the internal relation of land use and pollution load is the start of non-point source pollution research. At this base, many non-point source pollution models have been produced, such as SWAT. This paper mainly introduces the mechanism and study results of SWAT in the world, then makes a systematic prospect of its application in China.
