Research on the coupling of ecological environment and socio-economic development in resource-based cities: Based on scenario simulation method.

• Research on the coupling of EE and SE development in RBCs. • Improved the coupling coordination model for studying resilience levels. • A resilience level measurement model based on improved FCE has been constructed. • Using scenario simulation method to explore the path to achieve high coupling state. Resource-based cities (RBCs) encounter numerous challenges in terms of ecological environment (EE) protection and socio-economy (SE) upgrading. This exerts pressure on the advancement of sustainable development. A benign relationship between EE and SE is a crucial factor in promoting RBCs to realize sustainable development. Using Sichuan RBCs as a case study, this study determined the EE and SE resilience levels, examined the degree of coupling coordination between the two levels of resilience, and investigated the specific pathways in which RBCs might reach a high coupling state. The level of resilience in Sichuan RBCs is dropping for EE, stable for SE, and steadily increasing overall. The degree of coupling coordination is suboptimal, as shown by a D-value of 0.260. However, there is an overall trend towards improved coordination. There 8 cities with a moderate state of dysfunction. In the high state development scenario, the coupling coordination degree of the cities rises significantly. Guang'an, Luzhou, Nanchong, and Zigong should prioritize addressing the issue of EE pollution emission and work to strengthen the regulation and treatment of industrial pollutants. Moreover, to enhance the influx of talent and population, the cities of Dazhou, Guangyuan, Panzhihua, and Ya'an should implement human-centered urban design and layout. [ABSTRACT FROM AUTHOR]
