摘　　要：稀土开采破坏了生态环境,产生了大量的尾矿废弃地和严重的环境问题.概述了中国南方稀土尾矿区的污染现状和形成原因,综述了矿山土壤修复的物理、化学、微生物和转基因技术的研究进展,指出稀土尾矿生态修复过程中,植物修复优势种的筛选和土壤改良是关键,今后的研究应侧重于植物-REEs-微生物-土壤体系相互作用、REEs超富积植物及稀土矿区经济作物的筛选、新型土壤改良剂的研发.The rare earth mining has caused damage to the ecological environment,resulting in a large amount of tailings waste land and serious environmental problems.This article provided an overview of the current situation and causes of pollution in rare earth tailings mining areas in southern China.It reviewed the research progress in physical,chemical,microbial,and genetically modified technologies for soil remediation in mines.It pointed out that in the ecological remediation process of rare earth tailings,the selection of dominant plant remediation species and soil improvement were key factors.Future research should focus on the interaction between plants,REEs,microorganisms,and soil systems,screening of REEs enriched plants and economic crops in rare earth mining areas,and the development of new soil amendments.
