土壤可蚀性因子K值的初步研究

A Preliminary Study on the Values K of Soil Erosibility Factor

本文用美国新近建立的土壤可蚀性因子K值的计算公式和二次样条函数插值法转换的土壤质地,计算了我国南方主要的易蚀土壤的K值,结果表明,第四纪红粘土发育红壤和紫色土的K值较大。

Using newly developed calculating formula in USA and converted texture of soils by square spline function interpolation, the erodibility factor K values of the mainly erosive soils in South China were calculated. The results showed that, of those erosive soils studied here, red soil derived from Quaternary red clay and purple soil had higher K values.
