Identifying the Response of Ecological Well–Being to Ecosystem Services of Urban Green Space Using the Coupling Coordination Degree Model: A Case Study of Beijing, China, 2015–2023

Understanding the response of the ecological well–being to ecosystem services of urban green space is imperative for urban ecosystem conservation and management. However, few studies have focused on the response process and spatial relationship of ecological well–being to ecosystem services of urban green space in mega cities, while residents’ demand and evaluation of ecological well–being have not been fully considered. In this study, the ecological well–being evaluation index system was developed through integrating subjective and objective indicators. Using the main urban area of Beijing as an example, our results indicate that from 2015 to 2023, the ecological well–being has been continuously increasing. Moreover, this study indicated that the coupling and coordination degree between ecological well–being and ecosystem services of urban green space still need to be improved. In addition, three modes of spatial relationship were identified in this study: high coordination area, moderate coordination area, and low coordination area. The finding extracted from these spatial relationship models should provide references for urban green space planning to maintain sustainable urban ecosystem conservation and management.
