Abstract:

This paper established a comprehensive measure index system of urban resilience by combining four subsystems: economy, society, ecology and infrastructure, then evaluated the resilience of Chinese cities at the prefecture level, revealing its spatial and temporal differentiation characteristics and the influencing factors in the typical sample zone. The results show that: although the urban resilience subsystems gradually became balanced, the development trends of economic, ecological, infrastructure, and social subsystem are significantly different--economic subsystem is the dominant subsystem. The trend of agglomeration in the horizontal direction of urban resilience level is weakened, and the spatial development pattern of each subsystem is diversified. The spatial heterogeneity of urban resilience development is significant, with the cities in low-level and medium-low level are dominant and the eastern region is higher than the central and western regions. The spatial heterogeneity of urban resilience appears "clusterization", which shows that the resilience of urban agglomerations is higher than that of other regions. Urban resilience of the eastern coastal transect are significantly affected by urban vitality, while those of the Yangtze River transect are obviously affected by economic development, resilience of cities along the "Huhuanyong Line" is most affected by urban expansion factors.

Key words: urban resilience, comprehensive assessment of resilience, spatiotemporal disparity, prefecture-level city, China

摘要：

城市韧性对城市健康发展具有显著影响。本文从经济、社会、生态、基础设施等4个系统构建城市韧性综合测度指标体系，对我国地级以上城市韧性进行定量评估，揭示其时空分异特征，并对典型样带区进行影响因素探讨。结果表明：城市韧性子系统间逐步趋于均衡，但经济、生态、基础设施、社会子系统发展趋势存在显著差异，经济子系统占据主导地位，其他子系统位序转换加剧；城市韧性水平集聚趋势减弱，各子系统空间发展格局多样化；城市韧性发展空间异质性显著，中低、低韧性水平城市居于主导地位，东部地区整体高于中西部地区；城市韧性“集群化”空间分异特征显现，城市群地区的韧性高于其他地区；东部沿海样带受城市活力影响显著、在南北方向上变化相对缓慢，长江沿岸样带在经济大发展背景下呈现出明显的东西分异特征，而胡焕庸线沿线样带无明显差异、但其整体受城市扩张因素影响最为显著。
