摘要
根据唐山市2005—2019年土地利用变更数据和唐山市能源消费数据,测算出2005—2019年唐山市土地利用碳排放量,并分析其碳源、碳汇、净碳排放量及碳排放强度的演变趋势,通过LMDI模型进行碳排放驱动因素分解。结果表明:2005—2019年间唐山市土地利用碳排放量总体上不断增加,部分年份碳排放量较前年有所下降;唐山市的人均碳排放强度在研究期间呈现逐年上升的趋势,单位地区生产总值碳排放强度呈现逐年下降的趋势;影响唐山市碳排放最主要的正向驱动因素是经济效应,其次是人口规模和能源结构效应,负向驱动因素是技术效应。最后,通过对唐山市碳排放驱动因素的分析,对唐山市未来的节能减排和低碳经济的发展提出建议。
Based on the land use change data and energy consumption data of Tangshan City from 2005 to 2019,a calculation has been made of the carbon emissions from land use in Tangshan City from 2005 to 2019,followed by an analysis of the evolution trend of carbon sources,carbon sinks,net carbon emissions and carbon emission intensity,with the driving factors of carbon emission decomposed by LMDI model.The results show that the carbon emissions from land use in Tangshan City has been increasing from 2005 to 2019,with the carbon emissions in some years decreasing compared with the previous year.During the study period,the per capita carbon emission intensity of Tangshan City showed an upward trend year by year,while the carbon emission intensity per unit gross regional product kept decreasing year by year.Economic effect is the main positive driving factor affecting carbon emission in Tangshan City,to be followed by other factors as population size and energy structure effect,meanwhile the technological effect is the negative driving factor.Finally,an analysis is made of the driving factors of Tangshans carbon emission,with some suggestions put forward on the future development of Tangshans energy saving and emission reduction and low carbon economy.
