Abstract: With the disaster records of geological disasters in Qinghai from 2008 to 2019, and the CLDAS reanalysis precipitation data, the temporal and spatial distribution of meteorological geological disasters such as landslides, debris flows and collapses in Qinghai Plateau was analyzed. The variation characteristics of precipitation and soli moisture were studied, and the warning conditions were determined. The results show that there were 23 disasters in Qinghai Plateau in the past 12 years. Hazard-prone zones were located in Hainan Prefecture, Xining City, Huangnan Prefecture and Yushu Prefecture. July was the most frequent month of disasters. Effective rainfall and soil moisture are important factors affecting meteorological and geological disasters. Warning conditions are as follows: the accumulated effective rainfall on the same day and the previous day reaches 10mm or the continuous effective precipitation reaches 18mm; the difference of soil volumetric water content of 0~10cm and 10~40cm is less than 0.03mm³/mm³, or one of the soil volumetric water content more than 0.27mm³/mm³.
