Abstract
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.
