摘　　要：非点源污染已成为全球重要的环境问题,数学模型是当前非点源污染研究的核心内容。介绍了GIS与非点源污染模型的结合,并以SWAT模型为例阐述了基于GIS的数学模型在农业面源污染研究中的应用。Agricultural non- point source pollution is a ubiquitous environmental problem all over the world. Mathematic model is the critical part in research of non - point source pollution nowadays. This paper intends to discuss the necessity and significance of integrating non - point source pollution mathematic model with geographic information system （GIS for short）, and takes SWAT model for example to introduce the application of mathematic model based on GIS in aspect of agricultural non- point source pollution.

关 键 词：农业面源污染 地理信息系统(GIS) SWAT模型
