Taking the Central Yunnan Urban Agglomeration as a case study, this study constructs a framework for analyzing local and tele-coupling coordination relationships between urbanization and ecosystem health based on the "pattern-process" research approach. The findings reveal the following: 1) From 2000 to 2020, the level of urbanization showed continuous improvement in the Central Yunnan Urban Agglomeration, while ecosystem health initially deteriorated and later improved. Spatially, the two systems exhibited a dislocated pattern, with urbanization characterized by "high in the east of the Central Yunnan Urban Agglomeration and low in the west of the Central Yunnan Urban Agglomeration" and ecosystem health displaying the opposite trend of "high in the west of the Central Yunnan Urban Agglomeration and low in the east of the Central Yunnan Urban Agglomeration". 2) The local coupling coordination between urbanization and ecosystem health has gradually strengthened, with the main urban area of Kunming serving as the high-value core, radiating outward to the periphery, demonstrating a pronounced polarization effect. Simultaneously, the function of tele-coupling coordination has also improved, resulting in four telecoupling coordination axes with relatively balanced spatial distribution. 3) The degree of local and tele-coupling coordination between urbanization and ecosystem health has increased, transitioning from near imbalance to primary coordination. This trend features high-value clusters centered around regional central cities, with diffusion along the tele-coupling coordination axes. The influence of tele-coupling coordination has been growing, significantly supporting overall regional coupling and coordination. Differences in local and tele-coupling coordination effects are observed between core and peripheral areas, with peripheral areas relying more on tele-coupling coordination. Based on these findings, this study proposes spatially differentiated regulatory strategies that emphasize tele-coupling coordination, aiming to provide practical references for the coordinated development of urban agglomeration and ecosystem health.
