摘　　要：本文对１６５个红壤样品进行了可溶态稀土含量的测定，研究了可溶态稀土在土壤中的分布、土壤不同剖面层的分布及其所占比例的变化，探讨了土壤可溶态稀土含量与不同母质的关系，与土壤ｐＨ值（ｐＨＫＣｌ、ｐＨＨ２Ｏ）、有机质间的相关性，分析了与土壤硅酸盐成分及质地间的相关性。This paper deals with the distribution of soluable rare earth elements (REE) in red soils and different soil profiles,and also the change of percentage of REE in total soil contents. This paper also discusses the relationship between the contents of soluable REE in red soils and their different parent materials, soil pH values and organic matters,and analyses the relationship between the contents of soluable REE in red soils and the soil silicate composition,soil texture.
