随着城市化进程的加快,城市规模迅速扩大,城市人口与日俱增,与人们息息相关的城市生态环境问题越来越受到重视。近年来,各地政府纷纷投资建造绿地,见缝插绿,以提高城市绿化水平。但是,城市(尤其是老城区)可供绿化的用地紧之又紧,而可增加城市绿量的垂直绿化却又往往被忽视。 With the acceleration of urbanization, the scale of cities is rapidly expanding and the urban population is increasing day by day. The ecological environment of cities closely related to people has drawn more and more attention. In recent years, all local governments have invested in the construction of green space, sew plugging green, in order to raise the level of urban greening. However, the green space available for urban greening, especially in the old urban areas, is tight and the greening which increases the greening of urban areas is often neglected.
