| 摘 要： | 应用Visual Basic开发环境及Map Info MapX控件建立了一个非点源污染评价系统,并以浙江省剡江流域为试验区对其非点源BOD年负荷量进行了模拟计算,从系统的结构及运行过程,包括数据的输入、模型参数的提取、结果的可视化等方面分析了GIS在流域非点源污染评价中的应用,研究表明,将GIS技术应用于流域非点源污染评价能够有效地获取模型参数,增加了数据和评价结果的直观性,为流域非点源污染治理提供了一种有效的途径。

| Abstract: | This paper established an evaluation system for nonpoint source pollution integrated Visual Basic with MapInfo geographical information syseml(GIS) MapX and simulated BOD loads on annual average in the Yanjiang watershed in Zhejiang province in the case study. This study analyzed the application of GIS to nonpoint source pollution evaluation at the aspects of system frame and run process including data input, model parameters extraction, result visualization. This study indicated that integrating GIS technology with evaluation for nonpoint source pollution in watershed is effective in acquiring model parameters and enhancing the definition of data and evaluation result. It provided an effective method for nonpoint source pollution control in watershed. |
