According to the hydrogeological conditions and present situation of geological environment in Hengshui City, the index system for evaluating the supporting capacity of groundwater for the geological environment was established.Using expert scoring method and analytic hi-erarchy process, the weight of each evaluation factor was constructed.Using the comprehensive evaluation index method, the supporting ca-pacity of groundwater for geological environment was evaluated.The results showed that:land subsidence, brackish water interface move down obviously, the supporting capacity of groundwater for the geological environment is from moderate to weak from northwest to southeast.%依据衡水市水文地质条件和地质环境现状，建立了地下水对地质环境支撑能力评价指标体系，并采用专家打分法和层次分析法构建了各评价因子的权重，利用综合评价指数法评价衡水地区地下水对地质环境支撑能力。结果表明：该地区地面沉降、咸淡水界面下移严重，大部分区域地下水对地质环境支撑能力为中等到弱，从西北向东南的支撑能力越来越弱。
