摘要
以"一带一路"沿线中国西北地区交通碳排放强度为研究对象,采用Global Moran’s I、变异系数、Theil指数以及半变异函数模型等工具方法,对西北地区交通碳排放强度进行空间相关性和异质性特征分析。结果表明,在2006~2015年期间,西北地区交通行业所造成的CO_2排放量的增长幅度基本小于行业内部经济增长的幅度;空间相关性并未通过显著性检验;2006~2013年各向异质性角度在北偏东29°~51°之间变动,2014~2015年各向异质性角度介于北偏东113°~115°;次变程增减幅度较小,主变程变动较大,空间异质性范围变动明显。
Based on the carbon emission intensity in transportation in northwestern regions along the Belt and Road,this paper analyzes spatial correlation and heterogeneity characteristics of the carbon emission intensity in transportation in northwestern regions through adopting the Global Moran’s I,variation coefficient,Theil index,and semi variogram.The results show that from 2006 to 2015,the growth rate of CO2 emissions caused by the development of transportation is less than the internal economic growth rate;spatial correlation does not pass the test of significance;the angle of heterogeneity changes between the North East 29°and 51°from 2006 to 2013,and between the North East 113°and 115°from 2014 to 2015;the minor variation range is smaller and the main variation is larger,the variation of spatial heterogeneity range is more obvious.
