摘　　要：本文搭建了9种不同基质层的绿化屋面模块装置及人工模拟降雨装置,通过实验方法与模拟分析法研究株洲市绿化屋面对雨水产流时间、径流量及储蓄作用的影响。研究表明:绿化屋面相对于普通屋面均具有产流延迟作用和径流洪峰削减作用,产流最大延迟时间可达5.7倍,洪峰削减率可达38.7%。In this paper,nine kinds of green roofing modules and artificial simulated rainfall devices with different substrate layers were built.The influence of green roofing on the time,runoff and saving of rainwater in Zhuzhou City was studied by experiment and simulation analysis.The results show that compared with common roofs,the green roof has the effect of flow generation delay and flood peak reduction,with maximum delay time of flow generation up to 5.7 times and flood peak reduction rate up to 38.7%.
