摘　　要：以镇江市为研究对象,选取工程地质、地形、水文气象、自然生态和人为影响等5个主要评价因子,将研究区的建设用地适宜性划分为适宜建设用地、可建设用地、不宜建设用地和不可建设用地4个等级,利用层次分析法确定因子权重,结合GIS空间分析技术,得到综合的建设用地适宜性等级空间分布,4个等级的面积比分别为34.76%,23.29%,20.55%、21.40%。建设用地适宜性分析为镇江市城市规划和城市发展用地的选择提供了科学依据,也可减小城市发展对生态系统破坏的风险。Based on five impact factors of engineering geology,topography,hydrology and climate,natural ecology and human activity,this study evaluated the suitability of constructive land in Zhengjiang City.It can be divided into 4 classes of suitable land for construction,available land for construction,unsuitable land for construction and unavailable land for construction.Furthermore,the weight of factors was decided by analytic hierarchy process（AHP） and the spatial distribution of suitability of constructive land was obtained by combining GIS.The area rates of these four classes were 34.76%,23.29%,20.55% and 21.40%.The analysis of suitability of constructive land provides scientific references for urban plan and urban development,and can minimize the risk of urban development damage for ecological system.
