当今城市绿化空间需求不断增加，一种新兴的绿色开放空间类型——空中花园，在绿色开放空间中所占比重逐渐增大，如何设计与协调空中花园中的空间要素成为备受关注的重要问题。从空间 特征、植物景观、配套设施、服务管理 4 方面，对广州珠江新城范围内空中花园与地面绿地进行使用者满意度的调查，并结合 IPA–Kano 模型，通过环境特征的重要性和绩效评价，确定地面绿 地和空中花园中各环境特征优化的优先次序：在地面绿地中交通便利性、卫生设施、安全设施为优化第一优先级；在空中花园中空间开敞程度、休憩设施、卫生设施、安全设施为优化第一优先级。 最后，为优化基本型要素与提升游憩满意度，提出增强可达性与植物景观绿视量、改善配套设施使用体验与空间体验、完善配套设施、加强服务管理等建议。

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.
