Spatio-temporal Evolution and Influencing Factors of Carbon Emissions in Shaanxi Province
Based on DMSP/OLS and NPP/VIIRS nighttime light data,the carbon emissions from 2000a to 2020a in Shaanxi Province were estimated in this study.Meanwhile,the spatial-temporal evolution characteristics of carbon emissions were analyzed by the exploratory spatial analysis,hot and cold spot analysis,and the standard deviation ellipse analysis.The spatial Durbin panel model was also established to identify the influencing factors.The results indicated that:(1)The total carbon emissions of Shaanxi Province presented a continuous upward trend from 2000a to 2020a.It also exhibited distinct spatial and temporal heterogeneity with the characteristics of"Northern Shaanxi>Central Shaanxi>Southern Shaanxi"during the study period.(2)The distribution center of carbon emission had gradually moved to the northeast,which illustrated the carbon emissions in the northeast of the research area had increased more significantly than those in other regions.Carbon emission performed a significant positive spatial autocorrelation(i.e.,the agglomeration effect),and the transformations from hot spots to cold spots were also prominent.The hot spots expanded in northern Shaanxi,and the cold spots disappeared gradually.(3)Urbanization rate,population size,energy consumption per unit GDP,industrial structure and economic growth were all positively correlated with the carbon emissions in Shaanxi Province.The rapid development of urbanization and the expansion of population were the main driving forces for the carbon emission growth in Shaanxi Province.
