%X Based on the 30 m/8 d NDVI time series dataset of the Qinghai Tibet Plateau (2000-2020), combined with the "Remote Sensing Identification Data of Thermal Melting and Landslide in the Qinghai Tibet Engineering Corridor" and high-resolution PlanetScope images, LandTrendr and Segmented Linear Function Fitting (PWLF) methods were applied to identify and analyze the NDVI mutation process, revealing the key time nodes, disturbance amplitudes, and sustained effects of thermal melting and landslide disasters in the vicinity of the Chumar River on the Qinghai Tibet Plateau from 2010 to 2020. Multi source remote sensing image changes were used to verify its geomorphic disturbance mechanism. This dataset is suitable for monitoring surface processes in permafrost regions, analyzing the temporal sequence of landslide disasters, and studying regional ecological changes.
