【摘要】 针对当前城市面临的雨洪问题,低影响开发是一种基于生态学原理的可持续管理方法。而屋顶绿化建设作为低影响开发的有效实践方式之一,一方面具有一定的去除污染物的能力,同时可以削减屋顶雨水的径流量,延缓雨水的峰值时间;另一方面还促进了屋顶绿化技术的发展,不仅改善了其基础技术条件,拓展了屋顶绿化材料,而且丰富了绿化植物的选择范围。更多还原

【Abstract】 Low Impact Development of urban storm water drainage system is the planning and engineering design approach to manage storm water ecological and sustainable in urban area. Green roof construction is one of the most efficient practices to implement Low Impact Development. Green roofs can retain storm water, filter contaminants in the rainwater, increase green landscape and improve the local climate. And green roofs are also helpful to collect rainwater for treatment and recycle use.更多还原
