    摘要:

    [目的] 对皖西大别山区不同土地利用类型土壤抗侵蚀性进行研究,为防治区域水土流失提供理论支持。[方法] 测试并分析研究区不同土地利用类型下土壤崩解速率和土壤抗冲性指标。[结果] 土壤崩解速率V和抗冲性H在数值上随着坡位下降而增大,表明土壤抗侵蚀能力降低。不同土地利用类型土壤抵抗流水冲刷和水体分散能力的强弱关系均表现为:马尾松林地 > 茶园 > 荒地;表现在崩解速率V值方面,马尾松林地不同坡位分别为-0.16,-0.11和0.03 g/min,茶园分别为0.20,0.24和0.52 g/min,荒地分别为0.12,0.60和0.82 g/min。[结论] 不同土地利用类型下土壤崩解速率与抗冲性之间存在着良好的直线递增关系,其中,荒地土壤崩解性能随抗冲性变化速率最快,马尾松林地与茶园二者直线斜率差异不大。

    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.
