摘　　要：海绵城市建设能够增加自然降水对地下水的回补,减少城市开发对自然环境的破坏。然而,现有研究多集中于单一或典型LID设施,缺乏对大尺度和长周期海绵城市建设对整体地下水水位变化影响的探讨。论文基于Visual MODFLOW模型模拟了LID设施建设前后的研究区地下水水位动态。结果显示,LID建设典型区埋深上升0~2 m,降水对潜水的补给量增加了1.83%。这表明LID设施在局部区域能够显著增强降水对地下水的回补,但对整体地下水位的动态影响不明显。The construction of Low Impact Development(LID)facilities can enhance the recharge of natural precipitation to groundwater and reduce the environmental damage caused by urban development.However,existing studies mostly focus on individual or typical LID facilities,lacking discussions on the impact of large-scale and longterm sponge city construction on overall groundwater level changes.This study uses the Visual MODFLOW model to simulate the dynamic changes in groundwater levels before and after the construction of LID facilities in the study area.The results indicate that in typical LID construction areas,the groundwater depth increased by 0 to 2 meters,and the recharge from precipitation to the water table increased by 1.83%.This suggests that LID facilities can significantly enhance the recharge of precipitation to groundwater in localized areas,but have a negligible impact on the overall dynamics of groundwater levels.
