Abstract
The Qinghai-Tibet Plateau is the largest plateau in China, and the highest plateau in the world, which is known as ^roof of the world^. Climate change and human activities are having a significant impact on the ecosystems of the Qinghai-Tibet Plateau. Land cover data of the Qinghai-Tibet Plateau from 1970s to 2020 was obtained based on object-oriented classification method using Landsat and Sentinel2 images. The study shows that the largest area of the Tibetan Plateau ecosystem is the grassland ecosystem, which accounts for 55% of the total area of the Qinghai-Tibet Plateau in 2020. The changed landcover area between 1970s and 2020 accounts for 1.4% of the total area of the Qinghai-Tibet Plateau.
