摘要
土壤可蚀性是表征土壤对降雨渗透能力及其对降雨和径流剥蚀、搬运敏感程度的一个综合指标,是反映土壤侵蚀的重要参数。介绍了国内外学者提出的土壤可蚀性指标,评述了直接测定法、公式法和诺谟图法的优缺点与应用范围;结合我国土壤可蚀性研究现状,介绍了我国土壤侵蚀严重区的典型土壤可蚀性指标值的最新研究成果,分析了我国土壤可蚀性研究的不足,指出应加强并完善土壤可蚀性指标、土壤可蚀性影响因子和土壤可蚀性计算方法的研究。
Soil erodibility is an integrated index of soil characterization to percolation capacity of rainfall,sensitivity of precipitation or runoff denudation and transportation and an important parameter for soil erosion.The paper introduces the indexes of soil erodibility both at home and abroad,and comments on the advantages,disadvantages and scope of application of direct methods of determination,formula and nomogram.Then it lists the latest research results of index value of soil erodibility of the severe soil erosion region in China,and analyzes the insufficiency of the study on soil erodibility and points out that the study on index of soil erodibility,affecting factors and calculation methods should be further improved and strengthened.
