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.

Key words: transportation, carbon emissions, geostatistical analysis, semivariogram function, spatial-temporal evolution
