Abstract:To clarify wind erosion condition and impact factor, based on wind erosion theories and GIS technologies, this article selected opencast mine area of east Junggar Basin (Zhundong) as the study area, took the environment conditions of the study area into consideration, used field observation data and combined with meteorological data, the land use data, DEM, and remote sensing image to analyze the influence of soil wind erosion from 4 aspects: climate, soil, landform and vegetation coverage. In addition, the paper carried out a quantitative research on 4 impact factors, and used WEQ model in the study area with impact factors to evaluate and analyze the erosion grade. The results showed that: influenced by various factors, the wind erosion classification was obvious in study area, and erosion intensity showed a trend of increase from south to north. Severe erosion was the main erosion degree, accounting for 43.02% of the area. The average erosion modulus was 4 470.64 t/(km2·a), with wind erosion amount reaching 99.695 3 million tons. In order to verify the accuracy of the models, 137Cs trace method was used to comparatively analyze the model value. The verification results showed that the average relative error between 137Cs tracer method and the model value was 7.78%, proving that the model in the study area had good applicability.
