| 摘 要： | 选择赣南典型表生稀土矿区环境地球化学景观，研究了稀土元素在环境中的迁移规律，探讨稀土元素的迁移强度大小结果表明，该区环境中各稀土元素的水迁移能和大致排序为：（Ｔｂ，Ｅｕ）〉（Ｙｂ，Ｌｕ）〉（Ｓｍ，Ｎｄ，Ｌａ）〉Ｃｅ．稀土元素的生物迁移能力主要取决于植物的种属，轻、中稀土比重稀土元素相对易于被植物选择吸收。

| Abstract: | Transfer characteristics of rare earth elements(REE)in a typical environmental geochemical land-scape of super gene REE mine,southern Jiangxi province,were studied systematically.Results showed that the aquatic transfer coefficient of REEs have the sequence of:(Tb,Eu)>(Yb,Lu)>(Sm,Nd,La)>Ce,suggested that the tansfer capacity of the inter mediate REE,especially Eu and Tb are higher than the light REE and heavy REE.The biological adsorption coefficients of REE are mainly controlled by species of plant,and light REE relatively tend to be easy absorbed by some plants. |
