摘要
研究了福建分布在红土台地和不同比高河成阶地上的典型赤红壤和红壤的若干土壤化学特性,认为可按交换性Al^(3+),铝饱和度,ECEC的显著差异,将16个剖面划分成高级富铝化系列和中级富铝化系列2个组合,它们在地域分布上并不受传统水平地带性理论的控制。
Some chemical properties of typical lateritic red earthes and red soils distributed on the platform and fluvial terrace of various level in Fujian Province were studied. The results showed that sixteen soils could be divided into high and medium allitization series by the differences of exchangeable Al^(3+), aluminium saturation and ECEC. The gcophilic distribution of these soils did not accord with traditional theory of horizontal soils zonality.
