【摘要】：以中国30个省、自治区和直辖市为研究对象,以2000年和2012年为时间节点,运用自上而下法计算交通运输碳排放量,运用ESDA(探索性空间数据分析)和GIS(地理信息系统)相结合的空间分析框架探讨交通运输碳排放的时空格局特征.研究结果表明:1省域交通运输碳排放的增长速度和空间分异十分明显,东部经济地带中部经济地带西部经济地带,这与区域经济发展水平相一致;2交通运输碳排放呈现离散分布,负相关性不断减弱,热点区和冷点区比重均呈下降趋势,东部沿海尤其是长三角和环渤海出现热点结构特征,西部内陆始终为低值簇;3在不断扩大的交通运输碳排放空间差异中,随机性增强,空间自组织性减弱,格局演化存在一定的规律性和延续性,由东部沿海向西部内陆渐次倾斜.
[Abstract]:Taking 30 provinces, autonomous regions and municipalities directly under the Central Government of China as research objects, and taking 2000 and 2012 as time nodes, the top-down method is used to calculate the carbon emissions from traffic and transportation. Based on the framework of ESDA (exploratory Spatial data Analysis) and GIS (Geographic Information system), this paper discusses the spatial and temporal characteristics of carbon emissions from transportation. The results of the study show that the growth rate and spatial differentiation of carbon emissions from traffic and transportation in the province of: 1 is very obvious. The eastern economic zone, the central economic zone, the western economic zone, This is consistent with the level of regional economic development. The carbon emissions of transportation and transportation show discrete distribution, negative correlation is weakening, the proportion of hot spots and cold spots is decreasing, and the structure characteristics of hot spots appear in the eastern coastal areas, especially in the Yangtze River Delta and the Bohai Rim. The interior of the west is always low value cluster 3. In the expanding space difference of carbon emission in transportation, the randomness is enhanced, the spatial self-organization is weakened, the pattern evolves with certain regularity and continuity, and the eastern coastal area is gradually tilted to the inland of the west.
