Abstract: Taking Gansu Province as the research area, based on the calculation of land use carbon emissions in Gansu Province from 2000 to 2020, the Tapio decoupling model and LMDI model were used to analyze the influencing factors of land use carbon emissions. The results showed that from 2000 to 2020, the contribution value of land use carbon emissions in Gansu Province was 37.557 8 million tons, but the growth rate showed a significant downward trend. There was a weak decoupling between carbon emissions from land use and economic development,although the carbon emissions from land use caused by economic development continued to increase, this growth rate was slower than the economic growth rate, and the decoupling index continued to decline, gradually approaching a strong decoupling state.Economic development was the main reason for the increase in carbon emissions from land use in Gansu Province. Land use structure had a negative impact on it, while land carbon emissions density, economic development, energy utilization, and population size had a positive impact.

Key words: land use, carbon emissions, Tapio decoupling analysis, temporal characteristics, LMDI model, Gansu Province
