城市活力研究进展:尺度、测度与机制

Research Progress in Urban Vitality:Scale,Measurement and Mechanism

激发城市活力是实现城市高质量和可持续发展的重要途径。结合CiteSpace对国内外近20多年城市活力相关文献进行系统梳理,并对城市活力的研究尺度、外在表征和内在机制深入剖析。研究指出:活力研究在多个尺度和多种类型(如滨水区、公园绿地等)中均有涉及,但在轨道站域、街区等中观尺度相对薄弱;活力测度数据强调传统与新型数据多源组合,根据研究对象有所区别;活力影响因素指标多从前人研究衍生,如多样性、小街段、密度等,但不同类型研究对象影响因素存在差异,可根据具体研究对象特征进行调整和丰富。

To stimulate urban vitality is an important way to achieve high-quality and sustainable development in cities.Based on CiteSpace,a systematic review of literature on urban vitality in the past 20 years both at home and abroad is conducted,and an in-depth analysis is carried out on the research scale,external representation,and internal mechanism of urban vitality.The study points out that:(1)vitality research is involved at multiple scales and various types such as waterfront areas and parks and green spaces,but relatively weak at meso-scale vitality research in rail station areas,blocks,and other areas;(2)vitality measurement data emphasizes the combination of traditional and new data sources,which differs depending on the research object;(3)the indicators of vitality influencing factors are often derived from previous research,such as diversity,small street segments,density,etc.However,there are differences in the influencing factors of different types of research objects,which can be adjusted and enriched based on the characteristics of specific research objects.
