摘要

地理信息系统(GIS)具有强大的空间数据分析和可视化能力

可以反映非点源污染空间分布特性

将它与非点源污染模型结合可大大减轻非点源污染模拟难度。介绍了国内外非点源污染的研究现状

结合USEPA开发的BASINS系统及PLOAD模型

从数据的输入、模型参数的提取、结果的可视化3个方面分析了GIS在流域非点源污染研究中的应用

并以浙江省剡江流域为试验区进行了模拟

为此方面的研究提供了一定的借鉴。

Abstract

The Geographic Information System (GIS) has the strong abilities of spatial data analysis and visualization.It can reflect the spatial distribution of the non point source pollution.Integrating GIS with the non point source pollution model can greatly reduce the difficulty of non point source pollution modeling.The current situation of non point source pollution study in China and abroad is summarized.Combing the BASINS system and the PLOAD model developed by USEPA

the application of GIS in the study of non point source pollution in watersheds is analyzed from the three aspects of data input

parameter extraction and result visualization

and is simulated at the Yanjiang watershed in Zhejiang province as a case study.This analysis could provide some use for reference in this field.
