摘　　要：为研究生物滞留池滞留雨水径流和缓解城市渍涝的能力,通过模拟试验监测了生物滞留单元的入流和出流过程,研究其对雨水径流总量的削减率、洪峰削减率和洪峰出现时间延迟等的水文效应。结果表明,生物滞留池对径流总量的削减率在12.83%～48.12%之间,对洪峰的削减率平均为70.85%,延迟洪峰出现时间约26.6min,对小流量的洪峰延迟时间最长(达31.7min)。The aim of this research is to examine the reduction of runoff volume and flow peaks and peak time delay of the bio-retention units.Simulation test is adopted to monitor inflow and outflow process of bio-retention units.The hydrological effects of runoff reduction efficiency,reduction rate of peak,peak time delay are analyzed.The results show that the runoff volume reduction of the bio-retention units is 12.83%-48.12% while peak reduction is 70.85%;peak time delay is 26.6 minutes and the longest peak time delay is 31.7 minutes for little discharge.
