摘要
应用人工模拟降雨仪和Ｇｕｅｌｐｈ仪对我国南方低丘红壤区旱地土壤的渗透性与可蚀性之间的定量关系进行了研究．结果表明，第四纪红色粘土和红砂岩发育的旱坡地０～５ｃｍ表层土壤饱和渗透率Ｋｆｓ与土壤的可蚀性Ｋ呈现负相关，且它们之间的定量关系可概括为：Ｋ≈ａ·Ｋｆｓ－ｓ＋ｃ，其中ａ、ｂ、ｃ均为与土壤有关的系数。
In the paper quantificational relationship between soil permeability of upland and soil erodibility in hilly red soil region of southern China was studied, by using simulated rainfall and Guelph Permeameter. Results showed that there were negative correlations between saturated permeability Kfs of 0~5cm top soil and erodibility factor K of soil derived from Quaternary red clay and red sandstone, and the quantificational relationship can be expressed as K≈a·Kfs-b+c, where coefficients a, b and c were decided by soil properties.
