Abstract:: In order to reveal the pattern of coordinated development of urbanization and resources and environment carrying capacity and provide support to the high-quality development of urban agglomerations, taking the central Yunnan urban agglomeration as an example, we used the coupled coordination degree model and spatial autocorrelation and other analysis methods to analyze the spatial evolution characteristics of coupled coordination between urbanization and resources and environmental carrying capacity in 2000, 2010 and 2018. The results show that:(1)the average value of urbanization level index increased from 0.149 in 2000 to 0.359 in 2018, and the spatial development pattern changed from a single-core development in Kunming's jurisdiction to a development pattern of one main center and four secondary centers; the average value of resources and environment carrying capacity level decreased and then increased, and the average value of each year was 0.406, 0.402 and 0.442, and the internal differences of its spatial distribution were large;(2)the mean value of coupling coordination degree in the study area increased from 0.482 to 0.621, with a spatial distribution pattern of low in the northwest and high in the southeast; its Moran's I was greater than 0.42, showing strong spatial agglomeration;(3)during the study period, the spatial correlation between the coupling coordination degree, urbanization level, and resource and environmental carrying capacity was strong, but showed a decreasing trend; urbanization played the dominant role in the coordinated development; there was a negative spatial correlation between urbanization and resources and environment carrying capacity, and the bivariate Moran's I of the two decreased from -0.069 to -0.211, the spatial difference increased. By targeting to improve the weaker side in the spatial relationship, the coordinated development of urbanization and resources and environmental carrying capacity of the central Yunnan urban agglomeration can be realized.
