Abstract：This study is based on the socio-economic data related to land use and energy consumption in the Dongting Lake Eco-Economic Zone from 2000 to 2020,and it constructs a carbon emission calculation model.The standard deviation ellipse analysis method and LMDI model are used to analyze the spatiotemporal changes and influencing factors of land use carbon emissions in the region.The results show that,from a temporal perspective,net carbon emissions from land use in the Dongting Lake region exhibited an overall increasing trend from 2000 to 2020,and the economic development levels of different counties had a significant impact on net carbon emissions and carbon emission intensity from land use.From the perspective of spatial evolution characteristics,the spatial distribution pattern of land use carbon emissions in the Dongting Lake region from 2000 to 2020 remained stable;however,spatial autocorrelation was not significant,and the distribution shape showed a trend of flattening.From the perspective of driving factors,the level of economic development is the key factor driving the growth of carbon emissions from land use in the Dongting Lake region,while energy consumption intensity has suppressed the growth of carbon emissions to some extent..
