Abstract: [Objectives] The paper was to explore the spatio-temporal evolution of habitat quality in inland ecosystem. [Methods] Using landscape pattern analysis and InVEST habitat quality model, the land use change, landscape pattern and habitat quality change in Yunnan Province from 1980 to 2020 were studied. [Results] The land use change in Yunnan Province was relatively stable, and the forest land area accounted for 57.2% of the total area. The landscape fragmentation index caused by artificial surface encroachment on ecological land was increased by 6.33%, and the landscape heterogeneity was enhanced to varying degrees. The mean patch area was decreased by 5.83%, the number of patches was increased by 6.29%, and the degree of fragmentation was deepened. The habitat quality in Yunnan Province showed a “high-low-high” distribution from northwest to southeast, and the overall habitat quality was above the average. It is necessary to formulate optimization strategies to improve the regional ecological environment and realize the ecological system protection and rational land use in Yunnan Province. [Conclusions] The results will provide scientific reference for regional ecological protection construction and land use planning in Yunnan Province.
