| 摘 要： | 探讨了GIS技术在大气环境质量评价中的应用。依据大气环境质量指数评价模型,在利用GIS空间分析和属性查询功能的基础之上,对大气环境进行多因素复合分析,将城市大气污染因子的权重随区域差异按污染贡献率法进行赋值,即采用了一种基于"变权"思想的城市大气环境质量评价方法,并以合肥市为例进行了研究。研究表明该方法简单、合理,评价的结果与合肥市实际情况基本一致。

| Abstract: | The application of the geographic information system(GIS) in evaluation of atmospheric environment quality is described.Based on the index model of atmospheric environment quality and the GIS functions of spatial data analysis and attribute inquiring,the atmosphere quality is analyzed using the multi-factor composite method.Weight values of urban atmosphere pollution factors are evaluated in light of district difference and pollution contribution,i.e,on the basis of "variational weight" principle.This method is applied to the evaluation of the air quality of Hefei City,and the evaluation results accord with the practical situation,which shows that the method is simple and sound. |
