| 摘 要： | 为探讨红壤坡地土壤可蚀性K值特征,通过在典型的红壤坡地区建立15个标准径流小区进行连续5年的定点观测,运用诺模公式和EPIC公式计算红壤可蚀性K值,并对不同土地利用方式下的红壤K值进行分析。结果表明:2种经验公式均适用于红壤坡地土壤可蚀性K值计算,且K值与地表覆盖/土地利用相关。

| Abstract: | To study the laws of soil erodibility factor K on red-soil sloping land,fifteen experimental spots were established on the representative area to investigate runoff,sediment and soil properties from 2001 to 2005.Soil erodibility factor K was calculated by American nomogram formula,EPIC formula and field study,respectively.Then,K values of different lands with different utilizations were analyzed.The results showed that the two formulas can both be applied to calculate factor K on red-soil sloping land and K... |
