AB  - Snow disasters in the pastoral areas of the Qinghai Tibet Plateau are one of the important factors that plague and restrict the production of high-altitude animal husbandry. So far, a comprehensive and systematic investigation of snow disaster background data in pastoral areas and the establishment of a database have not been carried out. In response to this issue, the first and second projects of the "China Snow Characteristics Distribution and Survey" project, which focuses on the investigation of scientific and technological basic resources, will utilize ground investigation and remote sensing monitoring datasets on snow characteristics and distribution. A typical area will be established on the Qinghai Tibet Plateau, and high-precision snow data products (snow area, snow water equivalent, melting time) and ground investigation data on snow characteristics will be used. On the basis of considering comprehensive factors such as elevation distribution, grassland type, grass layer height, and socio-economic data in pastoral areas, a vulnerability model is established based on disaster data to determine the critical values of livestock mortality under different levels of snow disaster conditions. Based on the critical values, vulnerability zoning of disaster bearing bodies in various regions is carried out, and a hazard calculation model for disaster causing factors is established. Finally, based on a comprehensive consideration of the risk of disaster causing factors and the vulnerability of carrying bodies, a thematic map of snow disaster risk zoning in the pastoral areas of the Qinghai Tibet Plateau was produced. This achievement will be open and shared through a shared database platform, and will play an important role in various aspects such as agricultural and animal husbandry production and snow disasters in pastoral areas.
