WU Fangfang1, 2, CAO Yuee1, et al. Impact Factors of Soil Wind Erosion and Estimation of Soil Loss in Zhundong, Xinjiang[J]. 2016, 30(6): 56-60. DOI: 10.13870/j.cnki.stbcxb.2016.06.010.
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.
