| Abstract: |
| In this study, four sensitivity factors affecting the soil wind erosion of Zhundong area including wind energy intensity, vegetation coverage, relief degree of land surface and soil dryness were selected. Combining with GIS spatial analysis technique, the sensitivities of these factors were classified into five grades; extremely sensitive, highly sensitive, moderately sensitive, low sensitive and insensitive, and general analytic hierarchy process (AHP) was used to determine the sensitivity of the factor weight. Finally we determine Zhundong area comprehensive soil wind erosion sensitivity classification, distribution, and Zhundong area planning. The results showed that Zhundong area exist significant differences in the spatial distribution of soil wind erosion sensitivity, and the trend of wind erosion sensitivity in Zhundong area increased from east to west and from south to north; Extremely sensitive area, highly sensitive area, moderately sensitive area, low sensitive area and insensitive area occupied 15.27%, 17.20%, 22.66%, 17.20% and 25.38% of the total area, respectively. Some suggestions on the regional protection and construction were proposed. This study can provide a scientific reference for area economic development and environmental protection. |
