摘　　要：通过大兴安岭地区数据的宏观分析发现,微量元素低含量岩石形成的土壤中其含量增高,相反高含量岩石形成的土壤中其含量值降低。区域上微量元素在土壤中的分布趋向于均值,这种现象称为微量元素在风化过程中的"均一化"现象。不同微量元素的"均一化能力"不同。微量元素均一化特征的形成是大兴安岭地区成土因素综合作用的结果。The macroanalysis of trace elements in the Greater Xing'an Mountains showed that the element content in soil originated from rocks with high content is decreased relatively, on the other hand that of the soil originated from rocks with low content is increased relatively. The phenomenon that regional distribution of trace elements in soil tends to equalize to the average value was denominated element homogenization. The ability of homogenization is different for different elements. Trace element homogenization results from the soilforming synthetic acting factor.
