Abstract EN
The freeze-thaw (FT) erosion is a type of soil erosion like water erosion and wind erosion.
Limited by many factors, the grading evaluation of soil FT erosion quantities is not well studied.
Based on the comprehensive analysis of the evaluation indices of soil FT erosion, we for the first time utilized the sensitivity of microwave remote sensing technology to soil moisture for identification of FT state.
We established an estimation model suitable to evaluate the soil FT erosion quantity in Silingco watershed wetland of Northern Tibet using weighted summation method of six impact factors including the annual FT cycle days, average diurnal FT phase-changed water content, average annual precipitation, slope, aspect, and vegetation coverage.
Finally, with the support of GIS, we classified soil FT erosion quantity in Silingco watershed wetland.
The results showed that soil FT erosion are distributed in broad areas of Silingco watershed wetland.
Different soil FT erosions with different intensities have evidently different spatial and geographical distributions.
