Abstract: Based on the carbon emissions of tourism transportation in the Yangtze River economic belt from 2010 to 2021, this paper analyzes the change of spatial and temporal pattern, establishes the LMDI model from the perspective of transportation mode, and reveals the influence degree and change trend of influencing factors on the carbon emissions of tourism transportation. The results show that: 1） The overall carbon emissions of tourism transportation increase first and then decrease, which can be divided into a stage of slowing growth, a stage of stable development, and a stage of drastic decline. The railway rose steadily, the road rose first and then fell, the water was basically unchanged, and the aviation accounted for the largest proportion; 2） The spatial distribution pattern is high in the east and low in the middle. The high carbon emission areas are concentrated in the upstream and downstream areas, and the middle reaches are always the middle and low carbon emission areas; 3） Transport structure, energy efficiency, tourism consumption level and tourism scale are positive factors, while passenger and freight structure, energy intensity and tourism industry contribution are negative factors; 4） Among the positive factors, tourism has the largest scale effect and the lowest energy efficiency. Among the negative factors, the tourism industry contributed the most, and the energy intensity showed a downward trend. The difference of transportation mode is concentrated in the transportation structure, passengerfreight structure, energy efficiency and other factors are similar to the overall trend.
