Soil temperature has a major impact on soil fertility,plantation overwintering and microbial activities. Snow cover has albedo and insulation effect which will affect soil temperature and its freeze-thaw cycling in winter, and thus studying the impact of snow cover on soil temperature through effective model simulation is of great importance in the context of global change. The Snow Thermal Model ( SNTHERM) is a one-dimensional heat and mass transfer model,which is able to predict temperature profile within snow cover and frozen soil. In this paper,the model combined with the dynamic observation of frozen soil temperature,adopted the statistical parameters and Nash-Sutcliffe efficiency coefficient,is applied to assess the accuracy and efficiency of the simulation of temperature change process of freezing-thawing soil under snow cover. The results showed that SNTHERM is able to simulate effectively the changing process of daily mean soil temperature at the depths of 5, 10,15 cm under the snow cover with good agreement. The study revealed that the model having a good applicability under snow cover,which has improved the inversion accuracy of snow parameters. It is also suggested that the simulated accuracy of the soil water content will affect the simulated accuracy of soil temperature without snow cover,which reveals that considering the liquid movement in the model could improve the simulating accuracy.
