摘要
文中采用局部空间关联指数时间路径探究2007—2016年长三角机场群航空器碳排放的时空特征,使用对数平均狄氏指数分解法对其驱动因素进行分析,并提出措施建议.结果表明:①局部空间结构动态性低于总体水平的机场分布较为稳定;②演化过程曲折程度低于总体水平的机场占比大;③机场通达性和航线利用率因素促进碳排放增长;④客均座位数和能源强度因素抑制碳排放增长,但抑制作用有限.
The temporal and spatial characteristics of aircraft carbon emissions in the Yangtze River Delta airport cluster from 2007 to 2016 were explored by using the method of local spatial correlation index time path.The logarithmic mean Dirichlet index decomposition method was used to analyze its driving factors,and some measures and suggestions were put forward.The results show that:①The distribution of airports with local spatial structure dynamics lower than the overall level is stable.②The proportion of airports with a tortuous evolution process lower than the overall level is large.③Airport accessibility and airline utilization factors promote the growth of carbon emissions.④The number of seats per passenger and energy intensity factors inhibit the growth of carbon emissions,but the inhibition effect is limited.
