摘　　要：概述了稀土元素的环境生态学特性及其超积累植物,并对稀土元素超积累植物研究的重要科学意义进行了介绍。在此基础上,详细综述了近年来稀土元素超积累植物的研究成果,包括其种属、空间地域分布,其体内稀土元素的分布、分异特征及影响因素,其吸收富集稀土元素的生理及生化机制,并展望了稀土元素超积累植物及其修复应用研究的发展前景。A brief introduction of environmental and ecological characteristics of hyperaccumulators of rare earth elements （REEs）, as well as the scientific significance of REE hyperaccumulators were presented. Based on this, the achievements in REE hyperaccumulator research： （1） The species and regional distribution of REE hyperaccumulators, （ 2 ） Distribution and fractionation of REEs and their influence factors in hyperaccumulators were reviewed in detail, （3） Physiological and biochemical mechanisms of REE uptake by hyperaccumulators were reviewed. Furthermore, future directions in REE hyperaccumulator research and the remediation potential of REE hyperaccumulators were discussed.
