摘　　要：为了保障金陵河的生态基流量,同时增强地下水的循环速率与强度,本文以金陵河引洪入渗试验为例,运用数值模拟手段,研究洪水入渗地下的调蓄能力。结果表明:①约有24.9%的调蓄洪水增加了含水层的储存量,36.3%的调蓄洪水最终随地下水流排泄到金陵河,增加了金陵河的生态基流量;②调蓄洪水在含水层中储存并滞后了200 d。由此可见,洪水入渗地下充分利用了洪水资源,对研究区内水资源进行了时空上的再分配,调蓄效果显著。Aimed at insuring the ecological base flow of Jinling river and enhancing the groundwater circulation rate and intensity,the paper took flood infiltration experiment for example and applied the mean of numerical simulation to study the storage capacity of flood infiltration. The results indicate that about 24. 9% of the infiltrated flood is used to increase the aquifer storage,36. 3% of the infiltrated flood finally flows into Jinling river and increases its ecological base flow; the infiltrated flood is stored in aquifer and retards for 200 days. Flood infiltration is beneficial to making full use of flood resources,the method redistributes water resources spatially and temporally in the study area and shows remarkable storage effect.
