水源地碳排放时空演变特征及影响因素研究
Spatial and temporal characteristics and influencing factors of carbon emission in water sources
摘要
Abstract
Under the background of the"carbon peaking and carbon neutrality"goals,studying the spatial and temporal patterns of carbon emissions at the county level and their influencing factors is of great significance for promoting carbon emission reduction,low-carbon transformation,and the formulation of relevant regulatory policies at the local level.The Han River Basin,which serves as the water source of the Middle Route Project of the South-to-North Water Diversion Project,was taken as the research object.Based on the IPCC method and NPP-VIIRS nighttime lighting data,the carbon emissions of 67 districts and counties in the Han River Basin from 2013 to 2022 were estimated,and their spatial and temporal evolution characteristics were analyzed.Spatial autocorrelation analysis was applied to explore the correlation of carbon emissions in the counties of the basin,and the geographical detector and geographical weighted regression model were utilized to explore the influencing factors.The results show that from 2013 to 2022,the carbon emissions at the county level in the Han River Basin generally showed a fluctuating upward trend,and a spatial distribution pattern of high in the east and west and low in the middle was presented.From 2013 to 2022,the carbon emissions at the county level in the Han River Basin all exhibited significant spatial aggregation,and the characteristics of local spatial correlation aggregation were relatively stable in terms of time and space.Population density,total retail sales of social consumer goods,urbanization rate,total grain output,and general public budget expenditure were found to be correlated with the carbon emission levels in the Han River Basin,and each of them respectively had different spatial differentiation characteristics.关键词
