近两年,杭州积极推进“六位一体”低碳城市建设,其中有一项内容是实施城市“绿屋顶”计划。根据这个计划,新建项目有条件的裙楼应实施屋顶绿化,高架立柱、市政干道的边坡和挡土墙以及河岸驳坎都同步实施绿化覆盖,提高城市立体空间的绿色浓度, In the recent two years, Hangzhou has actively promoted the construction of a low-carbon city with a “six in one”, of which one is the implementation of the “green roof” plan of the city. According to this plan, the podium of the newly-built project should implement the greening coverage of green roofs, elevated pillars, the slope and retaining walls of municipal arterial roads and riverbank spreaders so as to enhance the green concentration of the urban three-dimensional space,
