摘　　要：为研究海绵工程生物滞留池的雨洪控制效果,基于MIKESHE模型构建滠水河流域雨洪模型,对比分析低影响开发后三种设计暴雨重现期下有、无生物滞留池场景下的流量过程,并设置六种不同生物滞留池空间布局方案,模拟十年一遇设计暴雨条件下低影响开发前后水文过程以评估不同方案的雨洪控制效果。结果表明:(1)不同设计暴雨下,布设生物滞留池场景可使峰值流量、径流总量分别减少1.08%~6.32%、5.64%~10.14%,产流时间延缓8~12h,且随着暴雨重现期的降低,峰值流量或径流总量的削减率、产流延后时间均增加;(2)雨洪控制效果最好的布局方案为上游布设生物滞留池,其布设总面积为16.9km2、蓄水深度为550mm;最差布局方案为在高程小于50m范围内布设生物滞留池,其布设总面积为4.1km2、蓄水深度为600mm。研究可为我国海绵城市建设、合理布控生物滞留池提供参考。To study the rainstorm control effect of sponge engineering bioretention,based on hydrological model MIKE SHE for Sheshui River Basin,discharge of three design storm events with or without bioretention of post-development were compared and analyzed.In addition,six different bioretention layouts were set and their rainstorm control effects were assessed based on modeling results of pre-development and post-development hydrological processes under 10-year return period.The results show that under different return period,the application of bioretention is able to reduce peak flow rates and total runoff volumes by 1.08%-6.32%and 5.64%-10.14%,respectively,and delay flow occurrence time by 8-12 h.Moreover,with the decrease in storm return period,both the reduction rate of peak flow rate or total runoff volume and delay time of flow occurrence increase.Among six different bioretention layouts,bioretention setting in the upstream of the basin has the best stormwater control effect,with a total area of 16.9 km2 and a detention storage of 550 mm.In contrast,bioretention setting below 50 m elevation of the basin has the worst stormwater control effect,with a total area of 4.1 km2 and a detention storage of 600 mm.This research can provide a reference for the construction of the sponge city in China and the scientific arrangement of bioretention.
