摘　　要：保持黄河不断流是傍河水源地存在的必要条件,黄河频繁的断流威胁傍河开采水源地的稳定性。本文建立了黄河下游影响带地下水系统模拟模型,模拟预测黄河下游在断流和恢复过流条件下,傍河开采时黄河侧渗量的变化趋势及傍河开采水源地地下水的演变趋势。研究表明:断流条件下,因傍河水源地开采而激发的黄河侧渗补给量增加幅度达28．4％-126．4％;小浪底水库运行对于傍河水源地实现稳定开采具有重要意义。To keep the Yellow River from flow cutoff is the necessary condition for allowing its riverside source fields alive. The frequent flow cutoff of the Yellow River threatens the stability of the water source fields. Thereby, the groundwater simulation model was set up for the groundwater system in affected zone of Yellow River, which can be used to simulate the transformation of lateral seepage or groundwater in the riverside source fields under the condition of flow cutoff and flow recovery. The study shows that the lateral seepage of Yellow River will increase by 28.4-126.4% comparing with that without riverside exploitation under the condition of flow cutoff. The running of Xiaolangdi Reservoir is important for the stable exploitation of river source fields.
