Abstract：The change of land use type by human activities is one of the main reasons for the increase of carbon emissions.It is helpful to realize the goal of"double carbon"to explore the spatial-temporal pattern and influencing mechanism of carbon emissions from the perspective of land use.Based on the remote sensing image data of land-use carbon emissions in Shanxi Province from 2005 to 2020,the temporal and spatial evolution,transition mechanism characteristics and influencing factors of land-use carbon emissions in Shanxi Province were studied by ESTDA method and LMDI decomposition model.The results show that:① From 2005 to 2020,the carbon emissions of land use in various prefecture-level cities in Shanxi Province increased year by year,but the spatial distribution pattern remained basically unchanged.② The overall spatial pattern and spatial dependence direction of carbon emissions from land use in Shanxi Province are relatively stable,but the spatial pattern of carbon emissions from Yangquan,Changzhi,Jincheng and Jinzhong fluctuates,and the spatial dependence direction of Shuozhou fluctuates;The evolution of the overall spatial pattern has strong spatial integration,high spatial cohesion and strong path dependence characteristics.③ The influence degree of carbon emission intensity of land use in Shanxi Province is increasing gradually,which plays a leading positive role,while land use level,economic development level and population number play a negative role.
