摘　　要：针对石家庄市利用南水北调水和当地雨洪水作为补给水源建设滹沱河地下水库过程中存在受水区和水源区具有不同年际变化特征的实际情况,在分析南水北调水源区汉江流域和受水区石家庄市降水丰枯遭遇特征的基础上,应用模糊数学和多维联合分布概率计算方法计算滹沱河地下水库的模糊加权补给水量,并应用数值法模拟各种丰枯遭遇条件下地下水库的人工补给效果。结果表明:不同丰枯遭遇条件下的补给水量为(4.64～8.72)×108m3/a,其中模糊加权补给量为6.66×108m3/a;人工补给可使地下水位多年平均回升1.47～3.45m/a;滹沱河地下水库的有效蓄水率为80%～90%,且人工补给的增大会引发侧向流出量增加,有效蓄水率相应降低。Considering the different annual variation between the resource area and accept area during the construction of Hutuo River groundwater reservoir,which uses the transfer water of South-to-North transfer water project and local floodwater as the recharge water,based on the analyses of precipitation encounters between Han River basin and Shijiazhuang City,applied fuzzy mathematics and multi-dimension combined distribution probability method in the analysis of precipitation plentiful-scanty encounter character between Han River basin and Shijiazhuang City,the fuzzy weighted recharge of groundwater reservoir in Hutuo River was calculated,and the artificial recharge effects under different plentiful-scanty encounter were simulated applied numerical method.The results show that,the available infiltrate water under different plentiful-scanty encounters has been calculated as（4.64-8.72）×10^8m^3/a,the fuzzy weighted recharge is 6.66×10^8m^3/a,artificial recharge can make groundwater level enhanced 1.47-3.45 m/a,the effective storage rates of groundwater reservoir are between 80% and 90%,because of the growth of lateral out-flow inspired by artificial recharge increase,the effective storage rates fall.
