摘要
青藏地区经济发展滞后,自然本底脆弱,开展能源碳排放时空格局演变及其驱动因素研究,对突破经济发展对能源消耗的路径依赖,降低生态环境代价具有重要的现实价值。基于青藏地区2005—2020年能源碳排放与经济发展数据,分析了碳排放的部门来源及其时空演化过程,并探讨了其内在机理。研究表明:(1)青藏地区能源碳排放规模15年间扩张2.37倍,增速显著高于全国其他地区,生态恶化和环境污染风险较高。(2)青藏地区能源碳排放重心主要位于高原北缘和东缘,研究期内空间格局总体稳定,但青藏南部生态脆弱区碳排放规模逐渐上升。(3)工业为青藏地区能源碳排放最主要来源,占比高达72.4%。服务业为增速最快部门,能源碳排放规模15年增长408.7%。(4)青藏地区总体处于“低经济发展水平-低能源消耗”的滞后发展阶段中,研究时段内交通与服务业能源碳排放与经济增长呈现增长连接和扩张负脱钩状态,经济发展产生较大环境压力。(5)青藏地区经济发展与能源碳排放具有紧密的因果联系,但影响程度具有明显的空间异质性。最后,基于青藏地区自然本底,经济发展,环境压力的三元互馈关系,探讨了不同区域经济发展与二氧化碳减排的协调路径。
As the third pole of the world,the Qinghai-Tibet region plays an extremely important role in the global ecosystem.However,the ecological environment threshold of the Qinghai-Tibet region has long been in a critical state,with fragile natural endowments that are easily disturbed and damaged by human activities.It is urgently needed to strengthen local environmental governance and reduce carbon dioxide emissions.At the same time,the Qinghai-Tibet region has harsh terrain and climate conditions,a sparse population,and relatively low levels of urbanization and industrialization.In this regard,it is imperative to improve the economic level to eliminate relative poverty and improve people′s livelihood.However,economic development inevitably consumes fossil energy and produces energy carbon emissions,conflicting with the regional ecological barrier positioning and ecological protection work.Therefore,studying spatial and temporal patterns of energy and carbon emissions and their drivers is critical to decoupling economic growth from energy use and reducing ecological/environmental costs.Using carbon dioxide emission panel data in 2005,2010,2015,and 2020 published by China City Greenhouse Gas Working Group,this paper analyzes the spatiotemporal evolution of energy carbon emission sources in the Qinghai-Tibet region and their driving mechanisms.Key findings include:Firstly,the carbon dioxide emissions have expanded 2.37 times over 15 years,growing faster than other regions in China.And this increase poses a serious risk to ecological degradation and pollution.Secondly,the center of carbon dioxide emissions in the Qinghai-Tibet region is mainly located along the northern and eastern edges of the plateau.The spatial pattern remained stable during the study period,but the scale of carbon dioxide emissions in the ecologically fragile areas of southern Qinghai-Tibet gradually increased.Thirdly,the industrial sector is the major source of carbon dioxide emissions in the Qinghai-Tibet region,accounting for as much as 72.4%of emissions.Moreover,the service industry is the fastest-growing sector,and emissions increased by 408.7%over 15 years.Fourthly,the Qinghai-Tibet region exhibits a feature of low development and low energy consumption.Meanwhile,the carbon dioxide emissions from transportation and services are positively correlated with economic growth.Fifthly,the economic impacts on carbon dioxide emissions vary spatially but exhibit a close causal relationship.Finally,considering natural,economic,and environmental interlinkages,pathways for coordinated regional development and emission reductions are discussed.The study aims to enhance macro-level understanding of the characteristics of energy carbon emissions in the Qinghai-Tibet region and provide a scientific basis for research on coordinated pathways between regional economic development and energy carbon reduction,to facilitate sustainable development in the Qinghai-Tibet Plateau region.
