R型因子分析和聚类分析在内蒙古伊山林场土壤地球化学测量中的应用

摘要

土壤地球化学测量分析元素众多,所成图件数量庞大,因此往往不易判断各元素之间的相关关系。笔者利用R型因子分析和聚类分析方法,对内蒙古伊山林场金矿普查区土壤样品进行分析,研究其元素间的共生组合关系。结果显示,R型因子分析和聚类分析二者对应性较好,有效地划分了元素共生组合类型。%Soil geochemical surve analysis numerous elements and The resulting maps are huge,it is often difficult to determine the relationship between elements.The soil samples in the yi shan forest gold census area of Inner Mongolia were analyzed by using R Type Factor Analyses and Cluster Analysis,the writer tries to study the association relationship between the elements.Results show that the R Type Factor Ana-lyses and Cluster Analysis has good correspondence between them,To divide the element assemblage.
