摘　　要： 综述了土壤中稀土元素含量、稀土赋存形态、稀土生物有效性、稀土在土壤环境中的分布规律、迁移方式及其影响因子。讨论了稀土微肥应用中应注意的问题以及由此带来的环境效应 ,并探讨了建立具有普遍适用性的稀土生物有效性方法学的途径等。 In this paper, concentration,speciation,bioavailability,distribution, and mo bility of rare earth elements (REEs) in the soil, as well as some relating facto rs were reviewed. Problems about REEs application as microelemental fertilizers, and consequently their potential environmental risks were discussed so as to pr ovide information for future research work. Finally, the ways to figure out an u niversal application method for bioavailable determinations of REEs were also di scussed.
