Abstract In this paper,based on the comprehensive analysis of the impact factors of soil freezing and thawing,the impact of the temperature and precipitation of China's climatic and environmental conditions on the freeze-thaw function and freeze-thaw erosion was discussed,and the overall distribution of freeze-thaw zones in China was defined.Based on the existing relevant research results,we explored and refined the classification standards of soil freezing and thawing,thus further explored the distributional range of freeze-thaw zones in China,finally described the regularity and characteristics of distribution and the features of freeze-thaw function and freeze-thaw erosion in the freeze-thaw zones.The results may provide the guidance for control erosion in freeze-thaw zones in China.
