摘　　要：从锰矿区废弃地重金属污染对周围环境的影响入手,综述了锰对植物的毒害作用和机理,列出了锰超富集植物的种类,分析了锰超富集植物的富集和解毒机制,并提出锰超富集植物筛选中存在的问题,最后展望了植物修复在锰矿区废弃地的应用前景,旨在为锰矿区废弃地重金属修复提供技术参考。Starting with the impact of heavy metal pollutants on surrounding environment in the lead-manganese（Mn） mine areas, a review was given on toxic action and mechanism of manganese to the surrounding plants, and the species of Mn hyper-accumulation were listed. The concentration and detoxification mechanism were analyzed and the current problems in screening of Mn hyper-accumulation plants were put forward. Finally, the application prospect of phytoremediation in lead-manganese mine areas was forecasted in order to provide technical reference in remediation of heavy metal.
