Exploring the coupling coordination of urban ecological resilience and new-type urbanization: The case of China’s Chengdu–Chongqing Economic Circle

Reviewing the coupling coordination between urban ecological resilience (UER) and new-type urbanization (NU) has gradually become a necessary condition for understanding the structure and service patterns of urban ecological systems. Discussion on the temporal and spatial coordination evolution in UER and NU in urban agglomerations with different characteristics is beneficial for understanding the operational mechanisms of urban ecosystems. This work constructs a novel evaluation framework for the coupling coordination process between UER and NU, and scientifically measures the performance of each indicator using the entropy method and CRITIC method. By using the coupling coordination degree (CCD) model, this paper explores the spatio-temporal effects of the relationship between UER and NU, which has narrowed the cognitive gap. Using the Chengdu-Chongqing Economic Circle in China as an example, the validity and practicality of the framework are verified. The results show that the CCD between UER and NU generally shows a rapid growth trend with time and tends to be balanced; and the development patterns of CCD in urban agglomerations show significant spatial differences influenced by factors such as location advantage, natural resources, and human social activities. These results and findings can provide decision-making information reference for urban ecological system services, urban livability, and government planning.
