- Abstract:
- The main reason for formation of soil desertification in northwestern Liaoning is the wind erosion. With respect to quantitative evaluation the Liaoning Northwest sandy soil under the action of wind, this study adopted embedded brazing method to observe the relationship between wind speed and soil erosion depth and stack depth. Soil erosion depth of fixed dunes and mobile dune increased with the increase of flow velocity; mobile dune and fixed dune, as the wind speed increased, the accumulation thickness increased in the middle and toe of soil leeward slope at different degrees, due to wind erosion action, the accumulated thickness at the top was negatively related to wind speed; the average intensities of wind erosion of the mobile dune, semi mobile dune, fixed sand dunes, were 167.9 mm/day, 57.8 mm/day, 4.2 mm/day, respectively, within one observed year.
