AB  - <pre><code>Snow disaster in pastoral areas of the Qinghai-Tibet Plateau is one of the important factors that perplex and restrict the production of alpine animal husbandry. So far, the investigation of background data of snow disaster in pastoral areas and the establishment of database have not been carried out comprehensively and systematically. In response to this problem, the ground survey and remote sensing monitoring data sets of snow cover characteristics and distribution in the first and second topics of the special project "Distribution and Investigation of Snow Cover Characteristics in China" of the scientific and technological basic resources survey project are used to set up a typical area in the Qinghai-Tibet Plateau, and use high-precision snow cover data products (snow cover area, snow water equivalent, snow melting time) and ground survey data of snow cover characteristics. On the basis of considering the comprehensive factors such as elevation distribution, grassland type, grass layer height, social and economic data in the pastoral area, and according to the disaster information, the vulnerability model is established to determine the critical value of livestock mortality under different levels of snow disaster conditions, and the vulnerability zoning of disaster-bearing bodies is carried out according to the critical value, and then the calculation model of hazard factors is established. Finally, a thematic map of snow disaster risk zoning in pastoral areas of the Qinghai-Tibet Plateau was prepared on the basis of comprehensive consideration of hazard factors and vulnerability of the bearing body. The results will be open and shared through the shared database platform, and will play an important role in agricultural and animal husbandry production, snow disaster in pastoral areas and other aspects.
