Abstract: Based on the snow density data from 1964 to 2003 in 29 meteorological stations, the temporal and spatial distribution of snow density in Xinjiang Uigur Autonomous Region was analyzed by using clustering and regression methods. The results showed that the snow density was significantly positively related to the precipitation, snow depth, strong wind, days of blowing snow and temperature. From this relationship, a model was established between snow density and above climatic factors. By using mapGIS65 and remote sensing data,the map of the snow density during the stable period was made.

Key words: Xinjiang, Xinjiang, Snow density, Stable period, Map of temporal and spatial distribution
