Abstract:Nowadays, the demand for urban green space is increasing. Hanging gardens, a new type of green open space, take an increasing proportion in the green open space. How to design and coordinate the spatial elements of a hanging garden has become an important issue that attracts much attention. In this paper, user satisfaction of sky garden and ground green space in Zhujiang New City, Guangzhou was investigated from four aspects: spatial characteristics, plant landscape, supporting facilities and service management. Combined with the IPA-KANO model, the importance and performance evaluation of environmental features were used to determine the priority of the optimization of various environmental features in the ground green space and sky garden. That is to say, among the environmental features of the ground green space, the environmental features in the first priority of optimization include traffic convenience, health facilities and safety facilities. Among the various environmental features of the sky garden, the first priority for optimization includes space openness, leisure facilities, sanitation facilities and safety facilities. Finally, in order to optimize the essential elements and enhance the satisfaction of recreation, suggestions were put forward to enhance accessibility and green vision of plant landscape, improve the use experience and space experience of supporting facilities, improve supporting facilities, and strengthen service management.
