The dataset includes three high-resolution DSM data as well as Orthophoto Maps of Kuqionggangri Glacier, which were measured in September 2020, June 2021 and September 2021. The dataset is generated using the image data taken by Dajiang Phantom 4 RTK UAV, and the products are generated through tilt photogrammetry technology. The spatial resolution of the data reaches 0.15 m. This dataset is a supplement to the current low-resolution open-source topographic data, and can reflect the surface morphological changes of Kuoqionggangri Glacier from 2020 to 2021. The dataset helps to accurately study the melting process of Kuoqionggangri Glacier under climate change.

The data set is the watershed scale erosion rate of the eastern Tibet Based on 10Be. The data includes the first author, publication year, longitude and latitude and erosion rate. The data were collected in published journal articles, and the data has significant spatial distribution characteristics, and different research results are consistent with each other. The spatial characteristics of basin-wide erosion rate are always related to river geomorphic characteristics (such as steepness), climate and tectonic activities. Therefore, the systematic data set can provide important data support for the analysis of the main controlling factors of regional erosion rate , making it possible to quantify the contribution of climate and structure to the surface process in the region.

Dating data of debris flow and dammed lake sediments in complex mountainous areas from 2019 to 2021. The data collection sites are complex mountainous areas prone to debris flow in the eastern and southern edges of the Qinghai Tibet Plateau. The experimental analysis is mainly completed in the salt lake chemical analysis and testing center of Qinghai Salt Lake Research Institute of Chinese Academy of Sciences and the analysis and testing center of Chengdu Mountain Institute of Chinese Academy of Sciences. The instruments used include RIS ø TL / OSL – Da – 20 automatic luminescence instrument, etc. The age data set of debris flow sediments in typical complex mountainous areas is established, the formation age of debris flow sediments in complex mountainous areas is quantitatively studied, and the ancient debris flow disaster activity history in complex mountainous areas is determined.
