Abstract: Accelerating the process of ecological civilization and enhancing the carrying capacity of resources and the environment in the region are important guarantees for Yunnan Province to become the vanguard of ecological civilization. Yuxi City, which is located in the Yunnan Central Urban Agglomeration, is one of the five major cities for economic growth in Yunnan. It is faced with the dual pressures of environmental protection and economic development. From the perspective of time and space, this paper screens and constructs an evaluation index system for bearing capacity of resources and the environment, and explores the spatial-temporal evolution characteristics of resource and environmental carrying capacity in Yuxi, in order to provide an analytical framework and practical basis for the economic and social development of the new era and development of resource and environment. The results show that the carrying capacity of resources and environment in Yuxi City has been continuously improved and the spatial differentiation is obvious. It is in a middle-high and low-international situation. There are common problems in high-speed economic growth, high resource consumption and large environmental pollution. In the future, it is necessary to strengthen the management of environmental pollution, increase the efficiency of resource utilization, promote the paradigm of circular economy, and promote the construction of regional ecological environment and sustainable economic and social development in the region.
