中文摘要：
城市化通过改变区域的下垫面条件,进而改变了天然状态下的水文机制.以济南某停车场为研究区域,假设该区域所设的调控措施为生物滞留池,运用SWMM软件建立模型,对加入调控措施-生物滞留池前后进行水文效应对比分析,并通过改变生物滞留池的深度、坡度等指标,模拟不同指标下的径流形态.研究表明：经生物滞留池调控后,洪峰流量呈显著减小的趋势,洪峰出现时间延迟;生物滞留池对于重现期较短的降水效果比较明显,重现期越长,效果越不明显.
英文摘要：
By changing the surface conditions of the region,urbanization,thereby we can change the hydrological mechanisms in the natural state.By using a parking lot in the United States,it can simulate the form of different indicators of runoff by modifying the detention pond depth,slope and other indicators.The results show that：The use of SWMM software simulates detention pond regulation.After a change of bio-retention,the peak flow is decreasing significantly,the peak time delays.The bio-retention is relatively large to reproduce the shorter return period.Moreover,the longer the period is,the more obvious the effect is.
