摘　　要：综述了超富集植物概念和判断标准的演变过程.在植物修复中,生物学特性、土壤环境和营养状况都影响到超富集植物对重金属的富集效率,还要克服超富集植物的地域性、生物量小等缺点.我国需要发现更多的资源,加强驯化、栽培和育种等方面的工作,才能为污染土壤的植物修复提供有力保障.The concept and criteria of hyperaccumulator and its evolution was reviewed.Many factors might impact the absorbtion and accumulator efficiency of hyperaccumulator,such as biological character,soil environment,and nutrient condition.Hyperaccumulators have endemic and less biomass features,these factors impact the effects of phytoremediation.In order to meet the needs of phytoremediation of soil pollution,much more species of hyperaccumulators will be discovered,at the same time,domestication,cultivation and breeding work of hyperaccumulators should be strengthen in China.
