基于地统计分析的中国省域交通运输系统碳排放时空特征研究

以30省域为研究单元，基于能源消耗测算了中国省域2003-2014年交通运输系统的碳排放量，探究了中国省域交通运输系统碳排放的时空分布特征及演变规律。结果表明：中国交通运输系统碳排放量持续快速增长，空间上表现为东高西低，南北方向呈"倒U"型的特征，且区域间相对差异逐渐减小。新疆、青海、甘肃这3省均为冷点地区，热点地区主要分布于东部沿海，历年交通运输系统碳排放重心基本位于河南省南部偏东地区，呈现东北-西南的方向格局，并向正北转变。不同时期交通运输系统碳排放数据变异的随机成分不同，且结构化差异呈减弱态势，而整体空间效应范围不断增大，溢出效应逐渐增强。

Spatial-Temporal Characteristics of China Transport Carbon Emissions Based on Geostatistical Analysis

Measurement and calculation were performed on carbon emissions produced by the transportation system in 30 provinces of China from 2003 to 2014 based on energy consumption by taking the provinces as a research unit. The temporal-spatial evolution of China's provincial transport carbon emissions was explored. Results show that:carbon emissions grew rapidly, and the eastern regions were higher than the western, space characteristics of north-south direction showed an inverted-U curve, and the difference between regions tended to be slight; Xinjiang, Qinghai and Gansu were cold spots, while the hot spots were mainly distributed in the eastern coastal regions, and the gravity center of carbon emissions was concentrated in the southeast of Henan province, with the directional pattern of northeast-southwest and a trend towards the north; random factors of data variation in carbon emissions during different periods were different, and the structural difference was weakened with an increasing overall spatial effect range and a gradually enhanced spillover effect.
