ABSTRACT

Global warming leads to the degradation of permafrost in the Qinghai-Tibet Plateau, which has an important impact on the growth and distribution of its vegetation. However, the reduction and destruction of vegetation may lead to the degradation or disappearance of frozen soil, which will have a large-scale impact on engineering buildings and frozen soil ecological environment in cold regions. There is serious spatial heterogeneity in vegetation growth and change in permafrost regions of Qinghai-Tibet Plateau, so it is urgent to quantitatively study the process of surface vegetation change along Qinghai-Tibet Highway. In this study, MODIS data was used to study the characteristics of vegetation growth along the Qinghai-Tibet Plateau from 2000 to 2021, and it was found that the vegetation on the east side of the highway was better than that on the west side. On the whole, the vegetation growth from 2000 to 2021 showed a slight upward trend.
