摘要
本文应用因子分析的方法,对新疆哈密盆地主要土壤类型中锌、锰、铁、铜四种微量元素的全量和有效态含量之间以及与土壤理化性质之间的相互关系进行探讨,指出用因子分析方法研究土壤分类及土壤中各种元素和土壤理化性质之间相互关系是一种可取的方法。
By means of factor analysis,the author researched ten physical and chemical indexes of 33 soil samples from Hami basin.Through Q-mode factor analysis, 33 samples may be divided into three groups,which corresponds with the soil types.Based on the R-mode factor analysis,ten indexes can be classified into two types.The total Zn,Mn,Fe and Cu in soils are closel related each other, and among availables Zn,Fe,Cu,Mn,organic matter and mechanical composi- tion,there is a close relationship.
