Research On Urban Resilience Evaluation And Spatiotemporal Differentiation Characteristics In Eastern China

Cities cannot be considered as solitary entities existing in isolation;rather,they manifest as intricate social-ecological systems necessitating the capacity to resolve issues under diverse circumstances.In this realistic framework,enhancing urban resilience and optimizing the functions of resilience bears profound implications for the healthy and sustainable development of cities.This thesis,under the theoretical guidance of pertinent literature on urban resilience,initially delineates the basic connotation of urban resilience.It lays a theoretical foundation in congruence with the theories of garden cities,complex adaptation,and core urban competitiveness.Subsequently,in alignment with the index system construction principles and system dynamics theory knowledge adopted by scholars both domestically and internationally,a comprehensive evaluation index system is established.Utilizing the entropy method to weigh the indices,it takes eleven provinces and cities,along with one hundred subordinate prefecture-level cities in the eastern region,as subjects of research.It measures the comprehensive resilience level and subsystem scores from 2006 to 2020.The aggregate resilience development level is the cumulative result of scores obtained from four subsystem dimensions: economic,social,ecological,and engineering.Lastly,transitioning from time to space,this thesis employs Arc GIS software to reveal spatial characteristics of the distribution of urban resilience levels in the eastern region.In combination with local and global autocorrelation theories,it explores the spatial correlation among various prefecture-level cities within the eastern region,delving deeper into the characteristics of spatiotemporal differentiation.The findings indicate that the level of comprehensive resilience is contingent upon the combined scores of all subsystems.Observing the variation in urban resilience levels across provinces,cities,and prefecture-level cities,the following salient points emerge: First,during the period from 2006 to 2020,Guangdong Province experienced a qualitative leap in its level of urban resilience,representing a noteworthy achievement among provinces and cities in the eastern region.Second,although the changes in the resilience of each subsystem are not entirely identical,the elevation in economic resilience level is the most conspicuous.Post 2010,social resilience and ecological resilience progressively contributed to urban development,bolstering the adaptive capacity of cities to withstand risks.Third,the alterations in urban resilience rankings among prefecture-level cities manifest evident spatial differentiation.Cities with extremely high comprehensive resilience levels and high resilience levels are predominantly clustered within the Shanghai metropolitan area,the Yangtze River Delta,the Pearl River Delta,and the Shandong Peninsula urban circle.A comparison of the spatial distribution of resilience across all subsystems reveals that cities with high ecological resilience levels exhibit the most balanced spatial arrangement.Fourth,spatial correlation exists among various prefecture-level cities in the eastern region.Therefore,further probing into the agglomeration patterns between cities using local autocorrelation is warranted.Throughout the period from 2006 to 2020,the overall spatial clustering pattern maintained by local autocorrelation did not undergo substantial alterations.This reflects the unyielding commitment of the eastern region to promote coordinated interlinkages around super-large and extra-large cities within their respective metropolitan areas.Figure [15] Table [35] See [72]...
