Abstract

The continuous deterioration of global climate is escalating the disaster risk for cities in the Chengdu-Chongqing urban agglomeration, and studying urban resilience is crucial for regional cities to prevent urban climate disasters and ensure sustainable urban development. However, few scholars discuss the mutual effects of urban social, economic and ecological resilience from the internal perspective of urban system. Therefore, this study puts forward the concept of urban resilience system, aims to measure the interaction effect between the rsubsystems' resilience of cities in the Chengdu-Chongqing urban agglomeration by coupling degree, and to measure the coordinated development effect between the rsubsystems' resilience of cities in the region by coordinating degree. Based on CRITIC–TOPSIS weighted evaluation model and revised coupling coordination method, the results suggest that (1) most cities have a low coupling degree of urban resilience system and are in the “Running-in stage”; (2) most cities have a low coordination degree of urban resilience system and are in the “Bare coordination” stage; (3) the coupling degree and coordination degree of urban resilience system are increasing in all cities with the development; (4) cities in the east and west of the region have better coupling degree and coordination degree than cities in the north and south; (5) the development of economic resilience and social resilience lags behind ecological resilience in most cities. The results could provide theoretical references for the practice of resilient city construction and urban resilience research.
