Spatial and Temporal Evolution of Carbon Emissions from Land Use and Its Influencing Factors Based on LMDI Model:A Case Study of the Dongting Lake Area
The spatial and temporal differences in land use,land use carbon emissions and their influencing factors in the Dongting Lake area from 1996 to 2020 were analyzed by using the carbon emission coefficient method and LMDI model.The results showed that:(1)The overall land use change was characterized by"three increases and three decreases",with construction land and unused land changing significantly,followed by waters and grass-land,and cultivated land and forest land changing to a least extent.(2)The total net carbon emission showed a rising trend,and the high carbon emission area shifted from central to southwest and east,the land use carbon foot-print pressure index was always much greater than 1 and was increasing at an average annual rate of 0.54.(3)GDP per capita,land use intensity per unit of GDP and carbon emission intensity per unit of land were the main factors of carbon emission from land use in the study area,and GDP per capita and land area per unit of GDP were the most important factors contributing to and slowing down the growth of carbon emissions in the Dongting Lake ar-ea,respectively.
