东北三省能源消费碳排放时空演变特征分析

Analysis on the Spatiotemporal Evolution Characteristics of Energy Consumption and Carbon Emissions in the Three Northeastern Provinces

双碳背景下,动态分析碳排放的时空演变特征,对低碳经济的发展具有重要的科学依据和应用价值。基于夜间灯光数据和相关能源数据,以东北三省及其各地级市为研究对象,测算并分析了2003~2020年东北三省能源消费碳排放时空演变特征。结果表明:① 从东北三省2003~2020年能源消费碳排放总量来看,能源消费碳排放总量呈逐年增长趋势,呈现出一种以中心城市为中心、辐射状扩展的态势。② 空间上呈现出东北部、西南部最高,中部最低的分异特征;各地级市碳排放总量存在明显的高值及低值区域。③ 碳排放具有显著的全局空间正相关,形成了以辽宁省的高碳集聚区和以吉林省的低碳集聚区为主的城市集聚态势。总体来看,东北三省能源消费碳排放整体呈现收敛态势,增长速率有所下降,但仍未达到碳峰值。

In the context of dual carbon, dynamic analysis of the spatial and temporal evolution characteristics of carbon emissions has important scientific basis and application value for the development of low-carbon economy. Based on nighttime light data and related energy data, taking the three Northeastern provinces and their prefecture-level cities as the research object, the spatial and temporal evolution characteristics of energy consumption carbon emissions in the three North-eastern provinces from 2003 to 2020 were measured and analyzed. The results show: ① Judging from the total carbon emissions from energy consumption in the three northeastern provinces from 2003 to 2020, the total carbon emissions from energy consumption show an increasing trend year by year, showing a trend of radial expansion centered on central cities. ② Spatially, it shows the differentiation characteristics of being highest in the northeast and southwest and lowest in the central part;There are obvious high and low value areas in the total carbon emissions of pre-fecture-level cities. ③ Carbon emissions have a significant global spatial positive correlation, forming an urban agglomeration trend dominated by high-carbon agglomeration areas in Liaoning Province and low-carbon agglomeration areas in Jilin Province. Overall, the carbon emissions from energy consumption in the three northeastern provinces have shown a trend of convergence, and the growth rate has declined, but has not yet reached the carbon peak.
