城市街道空间品质大规模量化测度研究进展

伴随我国人居环境建设从重“量”走向提“质”,城市建成环境的科学评估与定量研究亟待展开,街道作为重要的公共领域,其空间品质与活力成为重要的方向之一。本文从街道空间品质的概念、大规模量化方法和空间品质测度方法三个方面切入,梳理了国内、国外街道空间品质量化研究方法的进展。总体而言,街道物质空间的测度在不同的方面已有一定的方法积累、但少有多种方法的集成应用,利用可获得性高的街景图片进行街道空间测度是国际上新兴的研究方向,空间品质的影响机理研究还有待深入,已有研究少有以科学认识为基础的规划设计方法讨论。

LARGE-SCALE QUANTITATIVE MEASUREMENT OF THE QUALITY OF URBAN STREET SPACE: THE RESEARCH PROGRESS

The new normal era witnesses the policy shifting from growth planning to quality management. It is in urgent need to carry out the scientific assessment and quantitative research on the built environment. As street is an important public domain, its quality and vitality become one of the major research directions. Focusing on street space, this paper analyzes the existing quantitative approaches of street space in China and abroad from three aspects: the concept of street space quality, the large-scale quantification method, and the measurement method of street space quality. In conclusion, there are a number of measurement approaches for physical street space in various aspects, but the integrated application of the approaches is limited. It is a new research direction in the world to use street view pictures with high availability to conduct street space measurement. The influencing mechanism of the quality and vitality of street space still requires indepth research, and the discussion about scientific research-based street planning and design methods is lacked in existing studies.
