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％.
