摘要
本文为分析吉林省建筑业碳排放的变化趋势,以2004—2021年的建筑业碳排放数据为研究对象,运用碳排放系数法和能源平衡表建立碳排放测算模型,计算吉林省建筑业历年的碳排放量。采用对数平均迪氏指数分解(LMDI)模型对吉林省建筑业碳排放的影响因素展开分析,分解为能源消费结构效应、能源消费强度效应、人均产值效应以及人口数量效应4个影响因素。研究结果发现,建材生产阶段和运行使用阶段的碳排放量对吉林省建筑业的碳排放量变化影响最大,占96%以上,LMDI模型对这两阶段的碳排放总量进行分解提出各影响因素的影响程度由大到小依次排序为:能源消费结构效应>人均产值效应>能源消费强度效应>人口数量效应,总碳排放量的分解值为-21 039.97万t,16 988.64万t,6 772.04万t,-928.31万t。本文的研究结果可为吉林省建筑业碳减排工作提供一定的理论依据。
This paper to analyze the changing trend of construction carbon emissions in Jilin Province,to the construction industry carbon emissions data in 2004—2021 as the research object,using the carbon emission coefficient method and energy balance to establish carbon emissions measurement model,calculate the carbon emissions of Jilin Province,Based on this,the logarithmic average Dihlier Index Decomposition(LMDI)model was used to analyze the influencing factors of carbon emissions in the construction industry in Jilin Province,decomposition into energy consumption structure effect,energy consumption intensity effect,per capita output value effect and population effect four influencing factors.The research results show that the carbon emissions during the production stage and operation stage of building materials have the greatest impact on the changes in carbon emissions of the construction industry in Jilin Province,accounting for over 96%,LMDI model for the two stages of the carbon emissions decomposition factors by large to small order is:energy consumption structure effect>per capita output effect>energy consumption intensity effect>population effect,the decomposition values of the total influencing carbon variables were-210399700 t,169886400 t,67720400 t,and-9283100 t.The results of this paper provide a certain theoretical basis for the carbon emission reduction work in the construction industry in Jilin Province.
