The snow disaster risk zoning is conducted based on the climatic characteristics of less rainfall in spring and winter, great annual change rate of precipitation in Bayannur, and frequent snowstorm disasters, targeting at the days with snowfall greater than 3 mm, along with snow cover and freeze weather from November to next March of 1971 to 2010 The inter decadal variations of the numbers of snow days with snowfall greater than 3 mm, and snow depth greater than 5 cm are analyzed in combination with the historical records, field surveys, agricultural and animal husbandry production, and a variety of basic information and data, as well as GIS technology. From the aspects of hazard, vulnerability assessment and analysis, by using the methods of comprehensive weighting and Analytic Hierarchy Process, the snowstorm discriminating model is build, and the snow risk zoning of Bayannur is given on the NOAA satellite snow cover monitoring image. The risk zoning of snow disasters is useful to disaster prevention and loss reduction
