苏州市大都市外围地区空间绩效评价及演化机理

Spatial Performance Evaluation and Evolution Mechanism of Metropolis Peripheral Area, Suzhou

文章从社会经济、空间形态、土地利用、交通组织和生态环境五个层面选取 27 项具体指标,建立大都市外围地区空间绩效评价指标体系。随后,以苏州市为研究区域,从静态空间绩效分布和动态空间绩效演化两方面对苏州市大都市外围 5 个行政区进行综合评价,并重点分析空间绩效的演化机理。结果表明:①空间绩效分布受区域发展背景、城市基底和空间作用主体等多重因素综合影响,与城市空间格局关系紧密;②空间绩效演化趋势与城市发展时序及空间扩展趋势相吻合;③外围地区各子系统要素发展不均衡情况明显;④外围各区梯队化发展趋势显著。最后,文章从整合空间绩效需求、提升规划管控力度和协调多元主体利益三方面提出空间绩效的提升策略。

27 speci fic indicators are selected from five aspects, including social economy, space form, land use, traf fic organization and ecological environment to construct an evaluation system for space performance of metropolis peripheral area. Taking Suzhou as the research area, this paper comprehensively evaluates five administrative regions in Suzhou metropolis peripheral area from two aspects: static spatial performance distribution and dynamic spatial performance evolution, and focuses on the evolution mechanism of spatial performance. The results show that: 1) The performance distribution is in fluenced by many factors, such as regional development background, urban basement and spatial actors, and is closely related to urban spatial pattern. 2) The trend of performance evolution is coincident with the urban development timing and the trend of spatial expansion. 3) The unbalanced development phenomenon of the subsystem factors is obvious. 4) The echelon trend of peripheral districts is more obvious. At last, this paper puts forward three strategies to improve spatial performance from three aspects: integrating spatial performance needs, enhancing planning management and control, and coordinating multi-stakeholder interests.
