中文摘要：

选取我国南方某城市一条基于低影响开发（HD）理念建设的道路，利用InfoWorksICM城市综合径流模型模拟道路的降雨径流过程，评价生物滞留带的雨水滞蓄效果；另外，分析LID道路的场次径流总量削减率、峰值流量削减率、年径流总量控制率等指标及相关影响因素。结果表明，道路生物滞留带对中小降雨具有较好的控制效果，随着降雨量的增大，尽管统计所得的年径流总量控制率增大，但对降雨的径流总量控制能力减弱。

英文摘要：

Taking a road built based on the Low Impact Development （LID） conception which lo- cated in a southern city in China as the example, the rainfall runoff process was simulated using the In- foWorks ICM software to evaluate the effects of bio-retention facilities. The indicators of LID facilities such as the control rate of individual rainfall runoff events, the peak flow control rate and the capture ratio of annual rainfall runoff volume as well as the related influence factors were analyzed. The results showed that the performance of bio-retention facilities was better during the small and medium-sized rainfall e- vents. However, with the increase of rainfall volume, the control effects of individual rainfall runoff e- vents decreased, though the statistical data showed the capture ratio of annual rainfall runoff volume increased.
