摘　　要：通过对深圳市某道路生物滞留设施进行雨水径流监测试验,研究生物滞留设施对道路雨水径流的削减效果及影响因素。结果表明,当降雨总量为3.3~76.7 mm、平均雨强为0.03~0.67 mm/min时,生物滞留设施对道路雨水径流的场次径流总量控制率为50.5%~100%,峰值流量削减率为53.4%~100%,滞峰时间可以达到2 min以上。生物滞留设施对场次降雨量小且平均降雨强度小的道路径流削减效果较好。The runoff reduction effects of roadside bioretention facilities and the relevant factors to the bioretention efficiency were explored, based on stormwater runoff monitoring tests of a roadside bioretention facility in Shenzhen. The results showed that single event total runoff volume control rates reached 50.5% - 100%, peak flow reduction rates achieved 53.4% - 100%, and the peak flow was detained for more than 2 min, when the total rainfall volume was between 3.3 mm and 76.7 mm and the average rainfall intensity was between 0.03 mm/min and 0.67 mm/min. The bioretention facility demon- strated excellent performances in roadside rainfall-runoff control when rainfall total volume and mean intensity were low.
