摘　　要：对辽宁地区不同母质发育古红土剖面微量元素含量及聚类分析特征进行研究发现,成土母质是影响古红土微量元素含量、分布及其变化特征的首要因素,不同母质上发育的古红土微量元素含量有明显的差别,顺序为:千枚岩>石灰岩>第四纪松散沉积物>片麻岩。The microelement content characteristics of the paleosol developed from the different parent materials in Liaoning and hierarchical cluster analysis show that soil parent material is the primary factor affecting the microelement contents of paleosol and its distribution as well as the change in the characteristics. There is an evident difference in the microelement contents of paleosol developed from the different parent materials and the order is Phyllite〉 Limestone〉 Quaternary loose sediment〉 Gneiss.
