中文摘要:
      选取2005—2020年6期土地利用、能源消费等数据,从碳排放经济效率、能源消费结构和碳排放承载能力3个方面构建碳排放综合评价指标体系,运用改进Topsis法对新疆14地州市碳排放进行综合评价。结果表明:2005—2020年新疆碳排放总量由2735万t增长至18499万t,在碳排放经济效率、能源消费结构和碳排放承载能力方面均有不同程度的下降或恶化;研究期间新疆14地州市中有9个城市碳排放综合评价值呈下降态势,碳排放低效型、协调型和能源结构失衡型城市数量变化不明显,碳排放压力型城市数量增加。建议从优化土地利用结构、提升碳排放经济效率、能源结构转型方面进行碳减排管理。
英文摘要:
      This study selected the data of land use and energy consumption in 6 periods from 2005 to 2020, constructed a carbon emission comprehensive evaluation index system from the aspects of carbon emission economic efficiency, energy consumption structure and carbon emission carrying capacity, and comprehensively evaluated the carbon emissions in 14 cities in Xinjiang by improved Topsis method. The results showed that from 2005 to 2020, the total carbon emissions in Xinjiang increased from 27.35 million tons to 184.99 million tons, with varying degrees of decline or deterioration in carbon emission economic efficiency, energy consumption structure and carbon emission carrying capacity. During the study period, 9 out of the 14 cities in Xinjiang showed a downward trend in the comprehensive evaluation value of carbon emissions, the number of ci ties with low carbon emission efficiency, coordinated and unbalanced energy structure did not change significantly, while the number of cities with carbon emission pressure increased. Carbon emission reduction management should be carried out from the aspects of optimizing land use structure, improving carbon emission economic efficiency and transforming energy structure.
