摘　　要：通过对衡水市地下水系统特征的分析,建立了水文地质概念模型,并用FEFLOW建立三维地下水流数值模拟模型。应用识别与校正后的模型预测不同开采方案下的地下水动态。对于浅层地下水,方案1水位下降速率最慢,方案4水位下降速率最快;对于深层地下水,方案2水位最高,下降速率最慢,方案3水位最低,下降速率最快。从地下水资源可持续利用角度考虑,按方案2规划开采比较合理。The conceptual model of hydrogeology is developed based on analyzing the characteristics of groundwater system in Hengshui city, and a 3D numerical simulation model for the groundwater is developed by using FEFLOW. The identified and revised model is used to forecast the groundwater regime for different exploitation schemes. For the shallow groundwater, the elevation decline velocity of the scheme 1 is the slowest and the scheme 4 is the fastest. For the deep groundwater, the elevation decline velocity of the scheme 2 is the slowest and the scheme 3 is the fastest. Compared to other schemes the scheme 2 is relatively reasonable from the view of the sustainable utilization of the groundwater resources.
