Coupling coordination analysis of ecosystem services and urban development of resource-based cities: A case study of Tangshan city

Rapid urbanization has produced a series of impacts on the ecological environment. Many studies have extensively analyzed the relationship between urbanization and the ecological environment based on statistical data, but ignored the systemic functions of natural ecology. From the perspective of ecosystem services, we established an evaluation model of the coupling coordination degree (CCD) between urban development systems and ecosystems (UDES) based on ecosystem service value (ESV), and analyzed the dynamic characteristics and types of CCD between the two systems in Tangshan city. The results showed that the coupling coordination level of urban development and ecosystems in Tangshan City is gradually improving, but most areas have changed from lagging urban development to lagging ecosystems, and the contradiction between the two systems is increasing. Further analysis showed that water supply, environment purification, and hydrological regulation are the main factors affecting the coordinated development between urban development and ecosystems. The lagging interaction between the two systems requires policymakers to continuously pay attention to the change in ecosystem services and formulate appropriate regulatory policies to ensure the supply of ecosystem services. The research provides new thinking for achieving the coordinated and sustainable development of resource-based cities and ecology.

Automated summary

Rapid urbanization has had significant impacts on the ecological environment. This study aims to evaluate the coupling coordination degree between urban development systems and ecosystems, based on ecosystem service value. The results show that while the level of coupling coordination between urban development and ecosystems in Tangshan City is gradually improving, most areas have shifted from lagging urban development to lagging ecosystems, leading to an increasing contradiction between the two systems. Water supply, environment purification, and hydrological regulation are identified as the main factors influencing the coordinated development between urban development and ecosystems. These findings highlight the need for policymakers to continually monitor ecosystem service changes and formulate appropriate regulatory policies to ensure the provision of ecosystem services.
