| 摘 要： | 应用美国通用土壤流失方程 (USLE)和土壤侵蚀预报模型 (WEPP)中的土壤可蚀性K值 ,对四川各类自然土壤和旱耕地土壤可蚀性特征进行了研究。结果表明 :土壤可蚀性K值与土壤理化性质直接相关 ,自然土壤和旱耕地土壤可蚀性K值在 0 2 68～ 0 3 44之间 ,紫色土的分布面积和K值较大 ,是易遭受侵蚀的土壤。应采取增施有机肥、实行坡改梯等措施 ,加强对耕地、高可蚀性土壤侵蚀的综合防治

| Abstract: | It studies the texture of erodibility of varies natural soil and non irrigated soil in Sichuan by applying K value of soil erodibility of USA Universal Soil Loss Equation (USLE) and soil erosion forecasting model (WEPP). The results show that the K value of soil erodibility is closely related with physical chemistry of soil texture. The K value of soil erodibility of natural soil and non irrigated soil is between 0.268～0.344. The greater K value and distribution area of pale reddish soil is easily subjected to erosion. It should adopt the measures of applying more organic fertilizer, turning slope lands into terraces and strengthening comprehensive prevention and control of cultivated lands and high erodible soil erosion. |
