摘　　要：基于雨水花园的降雨入渗补给试验和HYDRUS-1D模型,系统分析了降雨重现期、降雨历时及关键设计参数对浅层地下水入渗补给与径流控制的影响。研究表明,在相似的降雨总量下,较长的降雨历时相比高降雨重现期更有助于增强地下水补给和径流控制能力,而高降雨重现期则显著降低这些效果,表现出典型的“超渗产流”模式。关键设计参数如汇流比、蓄水层高度和种植土层厚度对系统性能有显著影响。This paper used rainfall infiltration experiments in bioretention facilities and the HYDRUS-1D model to analyze the impact of rainfall recurrence periods,durations,and key design parameters on the replenishment of shallow groundwater and runoff control.Design parameters were optimized through calibration and response surface methodology scenario simulations.The findings reveal that,under similar rainfall amounts,longer rainfall durations are more beneficial for groundwater replenishment and runoff control than higher rainfall recurrence periods.Notably,higher rainfall recurrence periods significantly reduce infiltration and runoff control effects,aligning more with the"exceeding infiltration"model.
