Based on the observation data of ground and snow surface temperature from five weather stations at Changji from 2008 to 2010, the 0 cm maximum and minimum ground and snow surface temperature, cloudiness, sunshine duration, and snow depth dada are analyzed. The relation between snow surface and ground temperature at different snow depths is studied, and the relation model is verified with the snow depth data in 2011 from Tianchi Station. The results indicate that there are three snow depth demarcations in the relation of ground and snow surface temperature: 5 cm, 6 to 40cm, and greater than 40 cm. When the accumulated snow depth is between 0 to 5 cm, the ground temperature differs from snow temperature, obviously influenced by snow depth and weather conditions; when the snow depth is between 6 to 40 cm, the ground temperature is mainly influenced by snow depth; when snow depth is greater than 40 cm, the ground temperature tends to be unchanged.
