英文摘要Freeze-thaw erosion is one of the three major soil erosions in China, including wind erosion and hydraulic erosion, which leads to the destruction of the natural environment, the imbalance of economic development, a threat to personal safety, and irreversible disaster to the country and people. China's permafrost area accounts for about one-fifth of the country's land area, and the seasonal permafrost area accounts for half of China's land area, mainly concentrated in the Qinghai-Tibet Plateau, Xinjiang Province, Heilongjiang Province, Gansu Province, and other regions. In order to establish an evaluation system for the ecological function reserve of the Greater Hinggan Mountains, nine evaluation indicators were selected from the perspectives of topography, climate, soil, and vegetation conditions. GIS technology, a multiple collinearity test, and principal component analysis were used to comprehensively evaluate the freeze-thaw erosion in the ecological function reserve of the Greater Hinggan Mountains. This study categorized the evaluation results into five intensity levels, from micro to severe. Finally, the degree of influence of different influencing factors on freeze-thaw erosion and the interactions between the factors were analyzed using a geographic detector. The results showed the following: (1) The intensity of freeze-thaw erosion in the study area gradually increased from west to east, and the comprehensive evaluation results were -0.2552 to 0.7581. Overall, moderate, severe, and mild erosion accounted for 29.83%, 25.9%, and 21.54% of the total area of the freeze-thaw zone, respectively. (2) Soil moisture content and the annual range in temperature were the main factors contributing to freeze-thaw erosion. The degree of influence of the two effects on freeze-thaw erosion (q = 0.5997) was better than that of the single-factor effect.
