| 摘 要： | 在综合分析土壤冻融影响因子的基础上，探讨我国气候环境条件中的温度、降水对冻融作用与冻融侵蚀的影响关系，初步确定我国冻融区的总体分布。在以往研究基础上，探讨并细化土壤冻融分级标准，据此进一步探讨我国冻融区的一级、二级分区范围，阐述各冻融区的分布规律、分布特点及各区的冻融作用与冻融侵蚀特征。研究结果可为我国冻融区侵蚀的防治提供指导作用。

| 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. |
