Spatial-temporal evolution and influencing factors of carbon emissions in coal-based areas:taking the Shanxi as an example
Coal resource-based areas are the key regions of carbon emission reduction,whose ener-gy conservation and carbon reduction are of great significance to achieve the goal of carbon peak and carbon neutrality in China.In this study,nighttime light data of Defense Meteorological Sat-ellite Program/Operational Line Scanner(DMSP/OLS)and National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite(NPP-VIIRS)after fusion correction are used.The data model of carbon emissions from energy consumption and nighttime light is constructed to measure the carbon emissions of counties in Shanxi Province,a typical coal resource-based re-gion.Meanwhile,the exploratory spatial-temporal analysis and geographical detector are used to analyze the spatial and temporal pattern evolution and influencing factors of carbon emissions of all counties in Shanxi.The results show that:①From 2000 to 2020,carbon emissions in Shanxi show a growing trend,but the growth rate slows down significantly from 2010.②Carbon emis-sions show a significant positive global autocorrelation,forming a high-high agglomeration cen-tered on the provincial capital Taiyuan and Jinzhong,while low-low agglomeration is mainly dis-tributed in the western regions of Xinzhou and the eastern counties of Datong.③The level of eco-nomic development,population size,fixed asset investment and urbanization rate have a positive effect on the increase of carbon emissions,while the optimization of industrial structure has an in-hibitory effect on the increase of carbon emissions.
