Based on the meteorological data of temperature and precipitation at 62 stations on the Tibetan Plateau from 1961 to 2008(date for the Pulan and Gaize Stations is from 1973 to 2011)

the trend of snow disaster and its spatial characteristics were analyzed by using statistics and Kriging spatial analysis method. Results show that in the recent 51 years

the average of annual snow disasters increased and the number of station at which snow disaster occurred grew

especially after 1990. Snow disaster emerged mostly in early spring

secondly in former winter

and least in latter winter. The spatial distribution of snow disaster was uneven. Snow disaster occurred more frequently in the central plateau and southeastern plateau edge

in which higher frequencies of mild

moderate and heavy snow disasters were observed.
