摘　　要：通过对福州市地质环境问题的分析和研究,选择地质灾害易发程度、地震烈度、工程地质条件、地下水防污性能、地形坡度、土壤质量六个指标体系,利用层次分析法确定其权重系数,构造了福州市地质环境质量评价模型,基于GIS理论和技术,对其地质环境质量进行了定量评价。根据评价结果将福州市地质环境质量分为好、较好、中等、较差、差五个级别,分析了各区主要存在的地质环境问题。Taking Fuzhou city for example, this paper analyzes and studies on the geo-environmental problems. Geologic disaster occurrence level, earthquake intensity, engineering geological condition, groundwater vulnerab- ility, terrain slope, soil quality, six indexes are selected. Determining their weighty coefficients by the hierarchical analysis method and building the modes for assessing the geo-environmental quality of Fuzhou. The authors assess the geo-environmental quality of Fuzhou city quantitatively based on geographic information system. Then divideFuzhou city into 5 areas such as better, good,middle, bad, worse according to the result. At last, analyzes the main geo-environmental problems of each area.
