利用GIS的有关理论和技术,以沈阳市浑南新区为例建立了城市地质环境基础数据库,选择了区域地质环境评价的指标体系,并利用层次分析法确立了其权重系数,构造了区域地质环境评价模型。结果表明GIS与评价模型的结合可以高速、有效地进行城市地质环境的综合性评价。
Using the theory and technology of GIS,this paper takes Hunnan distri ct of Shenyang City as an example to establish the urban geo-environmental basi c database.According to appropriately guide line and measured weighed fact ors,an urban geo-environmental synthesis evaluation model is developed.
