中国能源碳排放时空特征分析

Spatial-temporal Characteristics Analysis of China's Energy CarbonEmissions

【目的】运用中国能源消费统计数据,分析中国能源碳排放时空分布特征。【方法】对中国2000—2019年30个省区市的碳排放总量进行估算,绘制相关分布图表,分析其时空特征,并提出合理建议。【结果】2000—2019年,中国碳排放总量增长约58.4亿t,年均增长幅度约为22.73%,不同省份的城市化程度分别与碳排放之间具有不同的相关关系。中国煤炭能源消费占比降低和碳排放量降低呈现出由沿海向内陆、由发达地区向落后地区倾斜的格局。【结论】建议加大节能技术研发投入,提高能源效率,合理调整能源消费结构,鼓励垃圾分类、植树造林等节约资源、保护环境的行为。

[Purposes]The article analysed the temporal and spatial distribution characteristics of energy carbon emissions in China using Chinese energy consumption statistics.[Methods]The total carbon emissions of 30 provinces,autonomous regions and municipalities directly under the central government in China for the 20 years from 2000 to 2019 are estimated,the relevant distribution charts are drawn,the spatial and temporal characteristics are analyzed,and reasonable suggestions are made.[Findings]From 2000 to 2019,China's total carbon emissions grew by about 5.84 billion tons,with an average annual growth rate of about 22.73%,and there are different correlations between the degree of urbanization in different provinces and carbon emissions,respectively,and China's reduction in the share of coal energy consumption and carbon emissions show a pattern of tilting from the coast to the inland,and from the de-veloped regions to the backward regions.[Conclusions]This paper suggests increasing investment in re-search and development of energy-saving technologies,improving energy efficiency,rationalizing the structure of energy consumption,and encouraging garbage classification,afforestation and other behav-iors that conserve resources and protect the environment.
