摘　　要：【目的】建筑屋面雨水是城市雨水径流的重要来源之一,对其资源化利用及适用性进行分析,有利于城市健康水循环的恢复和构建、城市生态系统的保护和修复。【方法】研究改进现有的建筑雨水排水系统,对屋面雨水进行截留、滞蓄,降低城市雨水排水系统的压力,使其与雨水资源化利用的目的相适应。【结果】与传统雨水排水系统相比,种植屋面、雨水花箱和垂直绿化等形式不仅可以有效排除屋面雨水,增加绿化面积,保温隔热,提高人们生活舒适性,还能对屋面雨水收集利用,降低市政雨水管网负荷。【结论】建筑屋面雨水资源化利用,对于缓解城市内涝危害风险,提高雨水资源利用率,都具有重要的现实意义。[Purposes]Rainwater on building roofs is one of the important sources of urban rainwater run⁃off.The analysis of its resource utilization and adaptability is conducive to the restoration and construc⁃tion of urban healthy water cycle and the protection and restoration of urban ecosystem.[Methods]This paper studies and then improves the existing building rainwater drainage system,intercepts and retains roof rainwater,and reduces the pressure of urban rainwater drainage system,so as to make it adapt to the purpose of rainwater resource utilization.[Findings]Compared with the traditional rainwater drainage sys⁃tem,planting roof,rainwater flower box and vertical greening can not only effectively eliminate the roof rain⁃water,increase the green area,keep warm,insulate heat,and improve people′s living comfort,but also strengthen the collection and utilization of roof rainwater and reduce the load of municipal rainwater pipe net⁃work.[Conclusions]Resource utilization of rainwater on the building roofs is of great practical significance for alleviating the risk of urban waterlogging harm and improving the utilization rate of rainwater resources.
