摘    要:城市地质环境评价是城市规划和场地选址的基础 .以兰州市为例 ,以地理信息系统软件ARC/INFO为开发平台 ,建立了城市地质环境基础数据库 ,将城市用地类型分为高层建筑用地、多层建筑用地、低层建筑用地、垃圾填埋用地及自然保护用地 ,系统分析了各类用地与地质环境协调性评价的指标体系 ,采用层次分析法建立了评价模型 ,对不同的用地类型进行了评价 .结果表明GIS与评价模型的结合可以快捷、准确地进行城市建设用地与地质环境的协调性评价

关 键 词:地理信息系统  城市用地  层次分析法  地质环境评价

Abstract:The urban geo_environmental assessment is a basic prerequisite for the urban planning and site selection. In this paper, the urban geo_environmental basic database including topography, surface and bedrock geology, depth to groundwater table and corrosion potential, lithology of bearing layer, and historic geo_hazards is established, with the Lanzhou city in northwestern China as an example, on the GIS_based ARC/INFO development platform. The urban land use is categorized as high_rise building, multi_story building, low_rise building, solid waste disposal, and natural conservation. The index system is systematically analyzed for the assessment of the coordination between various land uses and geo_environmental potential. Then the analytic hierarchy process method is employed to establish the evaluation model for different land uses, and geo_environment potential for each urban land use category is evaluated. The analytical results indicate that the combination of the GIS technology with the quantitative evaluation model can be applied to the fast and accurate assessment of the coordination between land uses for urban construction and geo_environment potential.
Keywords:geographical information system  urban land use  analytic hierarchy process  geo_environmental assessment
