Analysis of the Coupling Coordination and Obstacle Factors between Sustainable Development and Ecosystem Service Value in Yunnan Province, China: A Perspective Based on the Production-Living-Ecological Functions

The relationship and obstacles between sustainable development (SD) ecosystem services (ESs) are crucial factors for SD decision-making ecological conservation strategies. production-living-ecological (PLE) functional perspective provides a new research entry point to analyze the interrelationship of human society ESs. In view this, based on Sustainable Development Goals (SDGs), this study established an localization evaluation framework from PLE functions subsequently evaluated levels 16 cities in Yunnan Province 2005 2020. Furthermore, changes service value (ESV) were explored by combining land classification dynamic equivalence methods. ESV was then analyzed using modified coupling coordination degree (CCD) model. Finally, obstacle model introduced identify main affecting CCD level two systems. results revealed be high central region low other areas.
