核算了2003—2012年间中国30个省域的交通运输碳排放量和碳排放强度,分析了交通运输碳排放时空演变规律,分别计算了中国东、中、西部的交通运输碳排放量和碳排放强度的标准差和变异系数以定量分析其差异.结果表明:2003—2012年10年间,中国30个省域交通运输碳排放量呈逐年增长趋势,并整体呈现“西低东高”的特征,其中,湖北、广东和山东三省的总量居前3位,而内蒙古、吉林和重庆这3个省份(直辖市)的增速最快;交通运输碳排放强度整体上全国呈增长趋势,呈现出“西高东低”的非均衡变化特征;交通运输碳排放强度绝对差异增速趋缓,自2008年后三大区域的标准差和变异系数都呈现明显趋同效应.
The carbon emissions and carbon emissions of transportation in 30 provinces of China were calculated from 2003 to 2012. The spatial and temporal evolution of carbon emissions from transportation was analyzed and the transport carbon emissions and carbon emissions of the eastern, central and western China were calculated respectively Intensity of standard deviation and coefficient of variation to quantitatively analyze the difference.The results show that during the 10 years from 2003 to 2012, the transportation carbon emissions in 30 provinces and regions in China showed a trend of increasing year by year, and showed a “West Low East High” The three provinces (Hubei, Guangdong and Shandong) ranked the top three in terms of their growth rate, while the three provinces (municipalities directly under the Central Government) in Inner Mongolia, Jilin and Chongqing registered the fastest growth. The intensity of transportation carbon emissions in China showed an overall upward trend, presenting a The imbalanced characteristics of the “West-East-East-Low” have been observed. The absolute difference of carbon emission intensity in transportation has slowed down. Since 2008, the standard deviation and coefficient of variation of the three regions show a significant convergence effect.
