基于公众审美的城市绿地植物景观设计依据

An evidence-based study on plant landscape design in urban green spaces from the perspective of aesthetic preference of the public

针对当前城市绿地植物景观设计随意性较强和公众审美认知被忽视的问题,探寻了基于公众审美的植物景观设计的依据。以徐州城市绿地为研究对象,选取40个样地,对每一个样地的15个植被结构指数进行了现场测量或计算。每一个样地以一张具有代表性的照片为媒介,并以100名公众为评价人员,对各个样地的美学质量进行了定量评价。回归分析结果显示:增加灌木种类丰富度的同时降低乔木覆盖度可以有效提升城市绿地植物景观美景度。

In view of the arbitrary problem and ignoring public perception of aesthetics in current vegetative landscape, this essay tries to find the evidences of the vegetative landscape in urban green space based on the aesthetic preference of the general public. Forty sample sites were selected from the urban green space in Xuzhou, this essay measures and calculates 15 structural indices for each sample sites, were measured or calculated. One picture for each sample site was selected as the stimuli, and 100 members of the public were invited to evaluate the aesthetic quality of the pictures quantitatively. The results of sta- tistical analysis showed that enhancing the species richness of shrub and decreasing the arbor coverage were the reliable approaches to improve the aesthetic preference of plants landscape.
