摘　　要：黄河下游(河南段)影响带属于黄河下游冲积平原地下水系统,黄河对地下水的影响范围为5～23km,面积为9417.6km2。在建立水文地质概念模型的基础上,运用FEFLOW软件建立了研究区三维地下水流模拟模型,并对模型进行了识别。运用模型确定地下水多年平均补给资源量和可开采资源评价;预测新建傍河水源地开采条件下,地下水位在5～10年内趋于稳定;定量研究黄河与地下水的补排关系,傍河水源地开采量的65%～75%来自黄河水,黄河大堤防渗墙工程深度为20m和45m情况下,黄河侧渗量分别减小5.72%和8.12%。The affected zone of the Yellow River in Henan is part of groundwater system in the downriver alluvial plain, which ranges between5 to 23km along the river and the area is 9 417.6 km2. Based on the hydrological conceptual model, a 3D groundwater flow model is built and calibrated with FEFLOW. Groundwater resources and safe yield are evaluated using the model. The modeling results indicate: on the condition of planning development of groundwater near the Yellow River, the groundwater level will tend to be steady within 5～10 years, about 65%～75% of pumping rate derives from the Yellow River, and the seepage from the Yellow River reduces 5.72% and 8.12%, if the depths of the cutoff wall on the level are 20m and 45m respectively.
