| 摘 要： | 北京市永定河冲洪积扇中上部，具备建设地下水库的基本条件。本文在确定永定河地下水库水资源人工补给方式的基础上，分析了各方式的入渗能力，提出了地下水库的人工补给方案，利用地下水数值模拟的预测结果和有效储水率计算公式，首次研究了地下水库的储水能力，分析了永定河地下水库的水资源补给效果。结果表明，永定河地下水库水资源人工补给能力最大可达18．93m^3／s，回灌地表水2．42×108m^3的情况下地下水位最大回升32m，地下水储存量增加2．09×108m^3，回灌后1年和5年的有效蓄水率分别为78．6％和46．8％，北京永定河地下水库具有较好水资源回灌能力、储存能力，地下水人工调蓄能够起到明显的效果。

| Abstract: | The upper-middle of the Yongding River alluvial-proluvial fan meets the basic requirements to establish a groundwater reservoir. Based on the investigating thoroughly of the artificial recharge methods of the Yongding River groundwater reservoir, this paper further analyzes the infiltration ability of all recharge methods, proposes the corresponding artificial recharge engineer scheme. By the results of the numerical simulation of groundwater and the effective water storage rate formula, the groundwater storage capacity of the reservoir was first studied, and the effect of recharge of groundwater reservoir was analyzed. The result demonstrated that the maximum of recharge ability is 18.93m^3/s and the maximum of groundwater level rise is 32m, the groundwater storage is recovered about 2.09×10^8m^3 when the total artificial recharge quantity was 2.42× 10^8m^3. The effective water storage rate was respectively about 78.6% and 46.8% after 1 and 5 years. It indicated that the groundwater reservoir have preferable adjustment effect, recharge ability and storage capacity. |
