摘　　要：三峡库区地质灾害发育,已威胁到移民新城的城市规划与地方经济的发展。为解决这一问题,论文以巴东县新城区为研究对象,分析了滑坡的发育特征,开展滑坡灾害危险性区划研究,以MAPGIS软件为平台,根据斜坡坡向和斜坡坡度将全区共划分成223个不规则单元,采用层次分析方法构建评价指标体系,在得到信息量预测模型的基础上,对各影响因素指标图进行综合叠加计算得到了多因素作用的综合指标,在此基础上对该区斜坡稳定性进行了空间定量预测并编制了危险性预测分区图。预测结果为政府部门进行土地规划决策提供了科学依据。Geological hazards occur widely in the three-gorges reservoir region and threatens the urban planning and local economic development of the new immigrant town.In order to solve this problem,the new county-site town of Badong was selected for research on hazard zonation in this paper and the characteristics of landslides＇ development were described in the town.Based on the platform of MAPGIS software,the town is divided into 223 irregular units according to the direction and gradient of the slope.The evaluation index system was established by the Analytic Hierarchy Process and the integrated index affected by multi-factor was calculated by the superposition of every factors＇ index map based on the information value mode,the slope＇s stability was predicted quantitatively and the hazard zonation was compiled in terms of the results obtained by the information method,which will provide the basis for decision-making about the land development for the local government.
