Based on the county spatial scale and the 2000-2020 time scale (every 10 years), based on the analysis of land use change, this study conducted a study on the spatial-temporal evolution of carbon emissions and ecosystem service value, and analyzed the spatial correlation between land use carbon emissions and ecosystem service value. The effects of natural environment and social economic factors on the value of ecosystem services were discussed in order to provide reference for the scientific use and management of national land, the improvement of ecological environment quality and the development of low-carbon economy.
