    摘要:

    我国热带、亚热带的土壤资源丰富,类型繁多.土壤工作者对此作了大量的研究工作.关于运用数学手段进行土壤物质分类方面的研究,近年来也已发表过多篇文章.本文拟从土壤地球化学观点出发,采用数理统计学方法,对热带、亚热带土壤的地球化学类型进行物质分类.

    Abstract:

    The geochemical behaviour of elements in soils is closely related to their properties and soil development,as well as the bioclimatic condetion.And the contents of the elements in soil ate also related each othw.Ten major elements in soils were used for the principal component analysis in order to group the soils geochemically.On the basis of the principal component analysis,the soils of the tropical and subtropical China were distinguished in seven.types:the ferric.alditic,siferric,siallitic,quartzose-silicic,kamagnesian and the carbonated.The equation of principal component analysis was established for distinguishing soil E;eochemical type of a unknown soil.
