    Abstract:

    [Objective] Soil anti-erodibility under different landuse types in the Dabie mountainous area of Western Anhui Province was researched to provide basis for soil erosion control. [Methods] Soil anti-sourability and disintegration rate under different landuse types were tested and analyzed. [Results] Soil anti-sourability and disintegration rate increased with the drop of slope position, indicating a decrease in soil anti-erodibility. Landuse types, in terms of soil anti-sourability and disintegration rate, ranked in a descendant order as Pinus massonian woodland, tea plantation, and wasteland. The values of soil disintegration rate of different landuses were listed as follows: Pinus massonian woodland, -0.16,-0.11 and 0.03 g/min; tea plantation, 0.20,0.24 and 0.52 g/min; wasteland, 0.12,0.60 and 0.82 g/min. [Conclusion] For all the three landuse types, the relation between the anti-sourability and the disintegration rate presented obvious positive linearity. Soil disintergration rate for wasteland varied fast as soil anti-sourability changed and slope gradient of the linear equation was 0.246. There does not exist obvious difference between the linear equation slope gradient of tea plantation and that of Pinus massonian woodland.
