长三角城市群多部门碳排放的时空特征、影响要素与空间规划响应研究OA北大核心CHSSCDCSTPCD

In this paper,we visualize and analyze the spatial and temporal characteristics of carbon emissions in the Yangtze River Delta urban agglomeration from the perspective of total carbon emissions and emissions from the industrial,civil,transportation,and electric power sectors,construct a model to analyze influencing factors,and propose a response strategy from the perspective of territorial spatial planning.Firstly,the spatial and temporal data of carbon emissions in the Yangtze River Delta from 1990 to 2021 are visualized.Secondly,the spatial pattern of carbon emissions is analyzed through spatial autocorrelation.Thirdly,taking into consideration of national spatial planning zones,the improved STIRPAT model is used to select the factors and their elasticity coefficients of the socioeconomic and built-environmental factors that have significant impacts on the total amount of carbon emissions and the average per capita carbon emissions.Finally,spatial planning strategies for reducing carbon emissions in the Yangtze River Delta region are proposed.The results show that carbon emissions are clustered in the regional central city,and urbanization level,population factor,per capita wealth,and other factors contribute to regional carbon emissions.Based on this,spatial response strategies are proposed,including delineation of carbon emission zoning,guidance of low-carbon industries,and optimization of land use classification and pattern.
