摘　　要：地质灾害的种类繁多,且危害性极大,河北省高阳县由于地表水资源不足,长期开采地下水资源,导致区域地质灾害频发,主要表现为地面沉降和地裂缝。采用地震动峰值加速度、坡度、地下水开采模数、地质地貌、人口密度、水位、断裂带、土体结构及人均GDP分布特征作为危险评价因子,构建层次结构模型,对高阳县地质灾害危险性进行分区评价,并采用模糊评价法进行综合评价。研究结果表明:AHP-模糊综合评价法方法能够有效地对高阳县地质灾害危险性进行评价,高阳县地质灾害高、中、低危险区域面积分别占研究区总面积的41.51%、36.61%、21.88%。其中西演镇和庞佐乡高危险区域所占比例高达97.28%、96.08%。模糊评价结果显示高阳县整体地质灾害危险性等级为中等。There are many kinds of geological disasters,and the harm is great.Gaoyang County,Hebei Province,due to the shortage of surface water resources,long-term exploitation of groundwater resources,resulting in frequent regional geological disasters,mainly manifested as land subsidence and ground cracks.Using the peak acceleration of ground motion,slope,groundwater mining modulus,geological geomorphology,population density,water level,fracture zone,soil structure and per capita GDP distribution characteristics as risk assessment factors,a hierarchical structure model was built to evaluate the geological hazard risk in Gaoyang County,and the fuzzy evaluation method was used for comprehensive evaluation.The results show that the AHP-fuzzy comprehensive evaluation method can effectively evaluate the geological hazard in Gaoyang County,and the area of high,medium and low geological hazard areas in Gaoyang County accounts for 41.51%,36.61%and 21.88%of the total area of the study area,respectively.Among them,the proportion of high risk areas in Xiyan Town and Pangzuo Township is as high as 97.28%and 96.08%.The fuzzy evaluation results show that the overall geological hazard level of Gaoyang County is medium.
