绿化屋面雨水滞蓄效果研究进展

【摘要】 随着社会发展,城市建筑密度逐年增加,可渗透下垫面不断减少,城市洪涝频发,水资源短缺等问题催生海绵城市理念。绿化屋面是建设海绵城市的技术措施之一,能够有效滞蓄雨水,削减雨水洪峰,并延缓径流产生时间。针对绿化屋面的雨水滞蓄效果,本文概括了近年来国内外学者的研究成果,分析了绿化屋面在其基质厚度、植被类型、结构组成、降雨强度等不同因素影响下的雨水滞蓄效果,并展望了绿化屋面雨水滞蓄未来研究方向。更多还原

【Abstract】 With the development of society, the density of urban buildings increases year by year. The problem of decreasing penetra?ble underlying surface, frequent urban floods and the water Shortage promotes the development of sponge city. Green roofing is one of the technical measures of sponge city to store rainwater effectively.Green roof could reduce rainwater flood peak and delay runoff gener?ation time. In view of the effect of rainwater storage on green roofs,this paper summarizes the research results of scholars at home and abroad in recent years, and analyzes the effects of rainwater reten?tion on the influence of different factors such as substrate thickness,vegetation type, structural composition and rainfall intensity. This paper puts forward prospects for future researches on the rainwater runoff retention and detention of green roof finally.更多还原
