黑龙江省“十三五”期间市域碳排放时空分布特征研究

Study on the Temporal and Spatial Distribution Characteristics of Carbon Emissions During the 13th Five-Year Plan period in Heilongjiang Province

开展二氧化碳排放空间相关性以及空间分布特征研究对于指导区域实现“双碳”目标具有重要意义。此研究基于黑龙江省及下辖的13个市地“十三五”期间能源消费和GDP数据计算碳排放总量及碳排放强度,利用ArcGIS软件开展空间相关分析,探究黑龙江省省级层面的碳排放时空演变规律和市级层面的碳排放空间分布规律。结果表明:黑龙江省“十三五”期间碳排放总量及碳排放强度总体呈现出下降的趋势,但不具显著的全局空间分布特征。在局部空间相关性上,仅碳排放强度在伊春市呈现高-高聚集状态,而其他区域相关性并不显著。

Studying the spatial correlation anddistribution characteristics of carbon emissions is importantto guide the region achieving the goal of“dual carbon”.Based on the energy consumption data of Heilongjiang Province during the 13th Five-Year Plan period,this study calculated the total amount and intensity of carbon emissions.ArcGIS was used to construct the spatialcorrelation analysis including the spatial evolution pattern of carbon emissions at the provincial level and the spatial distribution difference of carbon emissions at the municipal level.The results show that the carbon emissions in Heilongjiang Province present a downward trend during the studied period while the local spatial characteristics of carbon emissions and intensity in Heilongjiang Province are not significant.In terms of local spatial correlation,only the carbon emission intensity in Yichun showed a high-high aggregation state,while the correlation in other regions was not significant.
