GIS的空间分析技术在长春市大气环境功能分区中的应用

APPLICATION OF SPACIAL ANALYSIS TECHNIQUE IN GEOGRAPHICAL INFORMATION SYSTEM TO FUNCTIONAL ZONE DIVIDING OF CHANGCHUN CITY'S ATMOSPHERIC ENVIRONMENT

综合定量地进行了城市大气环境功能分区 ,运用地理信息系统中空间分析技术 ,将城市社会功能、气象特征以及环境现状叠加来定量划分城市大气环境功能区。提出了地理信息系统支持下的分区方法及其步骤。

To get comprehensive and quantitative technique of functional zone dividing in city's atmospheric environment, the approach recommended in the paper is compartmentalize functional area quantificationally on the base of graphic overlay of city's social function, weather character and current environmental status by means of spacial analysis technique in GIS. The technique and precess of functional zone dividing in city's atmospheric environment is presented. By the example of functional zone dividing in Changchun City's atmospheric environment, The methods can quantitatively divide city's atmospheric environmental functional area.
