本文针对当前城市建设中绿化与建筑争地的普遍情况,探讨了解决矛盾的有效办法—充分利用建筑空间发展绿化。通过屋顶和平台绿化、墙面及阳台绿化、室内绿化等一系列实例,分析了各种绿化形式对城市环境所产生的美学和生态学效益。最后论证了向建筑索取绿化空间可以使城市总用地的绿化覆盖率增加到28.25～57.60％。 This paper addresses the prevailing situation of greening and construction competition in urban construction and discusses an effective solution to the contradiction - making full use of the development of the building space. Through a series of examples of greening of roofs and platforms, greening of walls and balconies, indoor greening, etc., the aesthetic and ecological benefits of various forms of afforestation on the urban environment have been analyzed. Finally, it was demonstrated that obtaining green space from the building can increase the green coverage of the city’s total land use to 28.25 to 57.60%.
