| 摘 要： | 大气污染扩散模拟过程中存在一些空间操作,例如确定污染源下风向的污染范围、坐标选择和转换和计算研究区域内任一点的污染物浓度。本文运用GIS组件MapObjects和VB.NET,应用GIS的空间分析技术,以惠州市惠城区为研究区域,实现了上述的三种空间操作,并与以往没有基于GIS的实现方法进行了比较。结果表明GIS的空间分析技术在大气污染扩散模拟中具有广阔的应用前景。

| Abstract: | There are some special operations in simulating air pollutant dispersion,such as Dividing polluted area leeward pollutant source,choosing and transforming coordinate,computing the concentration of one point in the researched region.According to special analysis technique in GIS,three special operations have been carried out in Huicheng district of Huizhou City on the basis of VB.NET and MapObjects.The method is compared with old one.By the example of Huizhou City,special analysis technique in GIS has prospective application in simulating air pollutant dispersion. |
