以南昌市某绿色建筑小区为研究对象,将该小区下垫面分成建筑屋面、硬质地面、绿地和水面四类,结合园林总体规划以及地形、水体和道路铺装等进行雨水径流管理的总体设计。从雨水的储蓄利用和促渗减排两方面着眼,在统筹兼顾雨水管理和园林景观两个核心目标的基础上系统布局雨水径流管理措施,实现了小区雨水径流管控和利用雨水补充景观水体、浇灌花草树木的目标,同时也避免了因雨水径流措施而导致小区园林景观碎片化的问题。
Taking a green building plot in Nanchang as the research object, the underlying surface of the plot is divided into four categories: building roof, hard ground, green land and water surface. According to the overall plan of the garden and topography, water body and road pavement, design. From the perspectives of saving and utilizing rainwater and promoting drainage and emission reduction, this paper systematically arranges stormwater runoff management measures based on the overall consideration of both the rainwater management and the landscape architecture, and realizes the regulation and control of stormwater runoff and the use of rainwater to supplement landscape water bodies and watering Flowers and trees of the goal, but also to avoid the storm runoff measures led to the fragmentation of residential landscape.
