摘要
相邻原则构造空间邻接矩阵,以全局自相关和局部自相关分析研究我国省域2000~2008年二氧化碳排放量空间差异性。全局空间自相关指数(Moran's I)统计值由2000年0.159增大到2001年0.202 9,后减小到2007年的0.197 9,继续减小到2008年的-0.034 9,趋势分析表明:中国省域碳排放量在2000~2007年之间存在空间正相关,且总体上呈减弱趋势,到2008年呈显著性很弱的负相关。对局部空间自相关指数分析确定了碳排放量的空间集聚模式及空间演变态势,其散点图揭示我国存在中东部碳排放量高而西部低的空间聚集现象。并对我国减少二氧化碳排放,走上低碳发展道路,实现全国经济健康、协调、可持续发展提出相关建议。
Based on space adjacent weights, global spatial autocorrelation and Local spatial autocorrelation are used to analyze Chinese provincial carbon dioxide emission, 2000-2008. The Global Moran's I value increases from 0.159 in 2000 to 0.202 9 in 2001, and then decreases to 0.197 9 in 2007, continuing to reduce to -0.034 9 in 2008. The Global Moran's I identifies that positive spatial autocorrelation which decreases slowly is presented between Chinese provincial carbon emissions. Local measure of spatial autocorrelation with local Moran's I reveals that provincial carbon emission tend to be spatially clustered in nature. There is a phenomenon that high carbon emission in the middle east of China and low gathered in the western of China. Some suggestions to reduce carbon dioxide emissions in order to adapt to the road of China's low-carbon economy are given in this paper.
