摘  要:
土壤可蚀性K值反映了土壤的抗蚀能力。对武夷山山地10个土壤剖面A层土壤可蚀性K值进行计算,结果表明:武夷山山地土壤以较低可蚀性为主,且呈现随海拔增高,土壤可蚀性K值逐渐递减的规律。一方面,垂直山地不同海拔有机碳的含量造成了土壤可蚀性K值的分异;另一方面,土壤可蚀性与土壤质地存在相互影响,土壤可蚀性K值与粘粒和粉粒含量均呈显著正相关,与砂粒含量呈显著负相关。

摘  要:
Soil erodibility K value reflects the erosion resistance.Through the calculation of the soil erodibility K value in A-horizon of 10 section planes of mountain soil in Wuyi Mountain,it was revealed that the erodibility of the mountain soil in Wuyi Mountain was mainly low and the soil erodibility K value tended to decrease as the altitude increases.On one hand,soil organic carton contents at different altitudes of Wuyi Mountain caused differentiation of K value.On the other hand,soil erodibility and soil texture could have influence on each other.Soil erodibility K was significantly positively related to the clay content and the silt content,while the sand content was significantly negatively correlated.
