Abstract: Remotely sensed dataset of grassland degradation in the Qinghai-Tibet Plateau (GLD_Tibet) is a production based on a related research about spatiotemporal changes of grassland degradation on the Qinghai-Tibet Plateau (QTP) over the periods of 1991-2000 and 2001-2012 using Sense's slope and Mann-Kendall trend test. During the 1990s, more than half (53.41%) of the grassland on the QTP was in some degree of degradation, but after 2000, more than three-fourths (78.62%) of the grassland had improved. The dataset provide scientific evidence for monitoring, assessment, and restoration management of alpine grasslands on the QTP, as well as the sustainable development and management of other grassland ecosystems.

Key words: Qinghai-Tibet Plateau, grassland degradation, remote sensing, spatial data
