ABSTRACT
As alternative public spaces in vertical public realms, sky gardens have become an increasingly important spatial element and part of the urban vocabulary in high-density environments worldwide. However, the public's spatial experience, social behavior and aesthetic needs in sky gardens have not been thoroughly explained. This paper takes Singapore, which has a rich social public space in the air, as an example where studies estimating spatial perception have used networked images instead of user preference survey results. Manual image identification and image recognition were performed with a computer vision application programming interface (API) to recognize networked images. Then, we extracted the sky gardens’ main elements in Singapore’s urban environment using clustering analysis, principal component analysis and factor analysis with SPSS. Finally, we discuss the spatial distribution, role and composition of sky gardens in high-density cities and people’s emotional preferences. The study shows that sky gardens are effective alternative public spaces in Singapore's vertical city, and their physical elements occupy a dominant position in the public’s spatial perception; there is a strong tendency for different buildings’ sky gardens to have spatial demand characteristics, while public facilities and cultural activities are key factors that affect sky gardens’ quality.

基于网络图片的空中花园空间特征研究——以新加坡为例
摘要
作为垂直公共领域的替代公共空间,空中花园已成为全球高密度环境中日益重要的空间元素和城市词汇的一部分。然而,公众在空中花园的空间体验、社会行为和审美需求还没有得到彻底的解释。本文以拥有丰富的空中社会公共空间的新加坡为例,估计空间感知的研究使用了网络图像而不是用户偏好调查结果。使用计算机视觉应用程序编程接口 (API) 执行手动图像识别和图像识别,以识别网络图像。然后,我们通过聚类分析提取了新加坡城市环境中空中花园的主要元素,用SPSS进行主成分分析和因子分析。最后,我们讨论了高密度城市空中花园的空间分布、作用和构成以及人们的情感偏好。研究表明,空中花园是新加坡垂直城市中有效的替代公共空间,其物理元素在公众的空间感知中占据主导地位;不同建筑的空中花园具有很强的空间需求特征,而公共设施和文化活动是影响空中花园质量的关键因素。其物理元素在公众空间感知中占据主导地位;不同建筑的空中花园具有很强的空间需求特征,而公共设施和文化活动是影响空中花园质量的关键因素。其物理元素在公众空间感知中占据主导地位;不同建筑的空中花园具有很强的空间需求特征,而公共设施和文化活动是影响空中花园质量的关键因素。
