Research progress on the effects of freeze-thaw on soil physical and chemical properties and wind and water erosion
Freeze-thaw erosion, one of the main types of soil erosion, is widely distributed in China. The distribution and harm of the combined erosion of freeze-thaw and other forces were greater than freeze-thaw erosion. We reviewed related research progress of the effects of freeze-thaw on soil phy-sical and chemical properties, wind erosion, and water erosion, based on literatures from China and abroad. Under the condition of freeze-thaw, soil water was transported and soil structure was dama-ged. Soil porosity, bulk density, shear strength, aggregate stability and organic matter were all changed. The change tendency and amplitude were related to soil texture and the degree of freeze-thaw. The occurrence and process of soil wind erosion and water erosion were influenced by the condition of freeze-thaw. Soil erodibility and erosion intensity increased as a result of the changes of soil physical and chemical properties. At present, the research on freeze-thaw mainly based on indoor simulation, which was quite different from the actual freeze-thaw process in the field. The conclusions obtained were not unified or even contrary due to different test conditions. Therefore, through combining indoor simulation and field survey, to strengthen the research of soil erosion mechanism of freeze-thaw conditions was the focus of the future research, which was of great significance for forecasting and preventing of soil erosion in the periods of thawing and the regions of seasonal freeze-thaw.
