Wenhui Liu, Hong Zhang, Jiaxin Ni
This paper focuses on the design strategy of roof gardens, analyzes the relationship between aerial greening from the overall shape of urban space, and discusses the greening spots effect of “stepping stones” in urban greenways. Taking the green corrider between the green space of the Yangtze River wetland and the green space of the Laoshan Mountain as a sample, the roof garden is analyzed as the impact of the stepping stones of the birds on the urban space shape control and height control. Afterwards, it researches the modular technology which can be adapted to building various types of roof gardens.
