Freezing soil is a natural phenomena in cold and mountain areas, which has great impact to the regional climate, water cycle, water balance and human activities. Permafrost against the 100 years of research show that the soil is frozen soil temperature, moisture and stress fields of common effects. Permafrost temperatures ranged from permafrost in the unique position of permafrost temperature permafrost research has become an important part of research, this paper introduces the permafrost temperature domestic development theory and research status, from the approximate calculation of the numerical analysis, measured from the scene of the computer simulation analysis, from one-dimensional to multi-dimensional theory of expansion. Permafrost temperature while the influence of the analysis, expounded the permafrost temperature on moisture movement for the promotion and transfer of water temperature counterproductive. Permafrost temperatures also study the mathematical description of the problem of note, citing the current use of the important research methods. A brief description of the permafrost study the problems that exist.
