[Objective] The purpose is to explore the coordination and development level among population, economy, and resources environment, clarify the coupling coordination relationship and influencing factors among counties, and provide strong support for the implementation of the main functional zone planning. [Methods] Based on the natural, economic, and cultural data of the central Yunnan urban agglomeration in 2010, 2015, and 2020, an evaluation index system for population-economy-resource and environment coupling and coordinated development was established from the perspective of the main functional area. The comprehensive weights were determined using the order relationship analysis method(G1)and entropy weight method(EW), and the coupling and coordinated relationship of each county was measured through the coupling and coordinated scheduling model, quantitative analysis of the population economy resource environment coupling and coordinated evolution of the central Yunnan urban agglomeration in 2010, 2015, and 2020, and exploration of its development laws. [Results](1)In the three periods, the population of the study area showed a positive spatial correlation at the county scale, and the spatial aggregation gradually increased, showing a low population density concentration in the western region and a high population density concentration in the central region.(2)From 2010 to 2020, population-economy-resources and environment coupling coordination degree had been slightly improved, and the seriously unbalanced development of coordination was gradually eliminated, barely unbalanced development accounted for 46.94% and became the main type of coordination.(3)The degree of coupling coordination between the two systems unevenly distributed, and the lowest population-economy coupling coordination index was 0.454 3 in 2020, its spatial distribution of coordination degree was most similar to that of comprehensive evaluation, which had a great impact on three system comprehensive evaluation results.(4)Before and after the implementation of major function-oriented zoning, the coupling coordination level of national key development zones changed significantly, the overall coupling coordination level of population-economy-resource environment was low and had a retrograde trend, and provincial key development zones were stable and controllable for a long time.(5)The relationship between the three systems in the study area had strong interaction relationship, but coordination was restricted to a certain extent. [Conclusion] The high coupling coordination mainly relies on the driving effect of population on the economy of cities, counties, and districts. The effective implementation of key development zones must focus on the coordinated development of population and economy, and the coordination between population and economy is the key direction for optimizing the main functional areas in the future.
