Evaluation and Spatiotemporal Evolution of Urban Comprehensive Resilience in Anhui Province

Resilience is a kind of characteristic that a city can self-regulate and continue to develop in the face of disaster risk. It is an important indicator to measure whether a city is healthy and safe, and also an innovative path to solve urban economic, ecological and social problems. It has important practical significance for the high-quality and sustainable development of a city. By means of CRITIC empowerment method, an urban resilience evaluation index system composed of economic resilience, social resilience, ecological resilience, infrastructure resilience and 20 indicators, including GDP, has been constructed, and the urban resilience level of 16 prefecture-level cities in Anhui Province from 2010 to 2020 has been measured. And I compare and analyze the development and change of the resilience level of each city in time and space. The results show that: (1) During the study period, the average resilience level of cities in Anhui Province has a certain degree of improvement and fluctuates with time, but the degree of disequilibrium among cities is deepened; (2) The overall resilience level of Anhui cities is low, and the provincial capital Hefei has an obvious advantage in resilience level, while other cities show a low and uniform distribution, and the average resilience level of marginal cities is low; (3) From the perspective of space, the average toughness level of central and southern cities showed an upward trend, while the index of most cities in northern Anhui showed a downward phenomenon. Finally, based on the analysis of the research results, the paper puts forward some countermeasures and suggestions to optimize the urban resilience of Anhui province.
