通过建立兰州“三滩”傍河水源地松散岩类孔隙水地下水流数值模拟模型，并根据研究区水文地质条件合理设计地下水应急开采方案，分析了应急开采对黄河水侧渗补给的影响以及水源地地下水位未来5 a 的演化趋势。结果显示，应急开采条件下，激发了黄河的侧渗补给量，随着时间的推移地下水补采平衡，5 a 预测期内傍河水源地地下水位未出现持续下降，预测期末水位趋于稳定。

The Santan Riverside Well Field(SRWF)is of important as emergency backup water sources in Lanzhou. A 3-D groundwater flow mod-el was built and the rational groundwater emergency programs were designed according to the hydrogeological conditions. With this model,the tend-ency of groundwater level was forecasted in the next five years and the impact of seepage of the Yellow River was evaluated. The results show that the lateral seepage quantity of the Yellow River increases by groundwater emergency exploitation. The groundwater level does not appear continuing decline and it is stable in the end of forecasting periods.
