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。 China’s tropical and subtropical soil is rich in resources and has a great variety of types. Soil workers have done a lot of research on this. Research on the classification of soil materials using mathematical methods has also published many articles in recent years. This article from the soil geochemical point of view, the use of mathematical statistics method, the tropical and subtropical soil geochemical types of material classification.
