Abstract: The Qaidam Basin (34°41′N–39°20′N, 87°49′E–101°11′E), a closed inland basin located in the northeastern Tibetan Plateau and surrounded by the Qilian Mountains, Altun Mountains and Kunlun Mountains, covers part of Qinghai Province, Gansu Province and Xinjiang Uygur Autonomous Region. The elevation of the basin is between 2391 m and 6826 m, with an average altitude of 4165 m. A large number of modern glaciers were developed in the Qaidam Basin. The glacial meltwater is an important source for the many rivers in the basin and a significant safeguard for local socio-economic development and people’s life. Therefore, glacier changes in the region have an important influence on water resources and their rational utilization. Based on the Landsat MSS/TM/OLI from 1977 to 2018 and the ASTER GDEM data, we extracted the glacier vector data of the Qaidam Basin from 1977 to 2018 . This dataset can be used as basic data for the study of glacier status, spatial and temporal distribution characteristics, glacier changes and their response to climate change in the region.
