采用政府间气候变化专门委员会推荐的方法,测算我国30个省市1997年、2002年、2007年和2012年能源消费和水泥生产产生的碳排放,并以碳排放强度为指标,运用分类比较、Theil指数和空间自相关分析(ESDA)的方法,研究碳排放强度的分布特征、地区差异和集聚现象。研究结果表明:1)我国各省市碳排放强度存在显著差异,整体碳排放强度向着低和中低水平的趋势发展;2)我国东部、中部、西部和东北4个区域,碳排放强度存在明显的地区差异,总体分布差异主要来自区域内差异;3)我国各地区碳排放强度呈现出正的空间相关性特征,L—L集聚区的省市数目呈增加趋势,H—H集聚区的省市数目呈下降趋势。
Adopting the method recommended by the Intergovernmental Panel on Climate Change to measure the carbon emissions from energy consumption and cement production in 30 provinces and cities in 1997, 2002, 2007 and 2012 in China. Using the carbon emission intensity as an indicator, Theil index and the spatial autocorrelation analysis (ESDA) method to study the distribution characteristics of carbon emission intensity, regional differences and agglomeration phenomenon. The results show that: 1) There is a significant difference in carbon emission intensity among all provinces and municipalities in China, and the overall carbon emission intensity tends towards low and medium-low levels; 2) There is significant carbon emission intensity in four regions of eastern, central, western and northeastern China Regional differences, the overall distribution of differences mainly from the regional differences; 3) China’s carbon emissions intensity in all regions showed a positive spatial correlation characteristics, L-L concentration of provinces and cities showed an increasing trend, H-H concentration of provinces and cities The number showed a downward trend.
