Abstract:

There is an interactive relationship between the soil desertification process and the driving factors of wind erosion in Horqin Sandy Land. The authors selected the Normalized Difference Vegetation Index (NDVI), surface albedo (Albedo), and humidity (Wet) indicators to construct a Desertification Difference Index (DDI), and divided the degree of desertification into four levels: including non-desertification, mild desertification, moderate desertification, and severe desertification. The RWEQ model was used to calculate the soil wind erosion modulus, and the control variable method was adopted to calculate the anthropogenic wind erosion and climatic wind erosion. By comparing their changing trends, the dominant factors of the soil desertification process were analyzed. The dataset supporting the findings includes: (1) boundary data of the study area; (2) degree and trend of desertification in Horqin Sandy Land from 1995 to 2020; (3) annual average soil wind erosion intensity and trend in Horqin Sandy Land from 1991 to 2020; (4) relative contributions of climate change and human activities to land desertification. The dataset is archived in .shp, .tif and .xlsx formats, and consists of 78 data files with data size of 2.29 GB (Compressed into one file with 822 MB). The analysis paper based on the dataset will be published on Acta Geographica Sinica, Vol. 81, No. 1, 2026.
