摘要: 阐述了植物修复的基本概念及主要作用方式,并从土壤中重金属存在形态,植物对重金属吸收、排泄和积累以及植物生物学特性与植物修复的关系等方面讨论了重金属污染土壤植物修复的基本原理及局限性和限制性因素,从超富集植物性能强化和技术强化两方面探讨了植物修复的强化措施,并指出与现代化农业技术相结合是植物修复重金属污染土壤大规模商业应用的一条捷径。

Abstract: The basic concept and main ways of phytoremediation were illustrated.The basic principles,restrictive factors and strengthening measures for phytoremediation of soils contaminated by heavy metals were discussed according to their relationship with compounds and forms in the soils.Uptake,excretion and accumulation of plant to heavy metals,biological traits of hyperaccumulators,and the capability and improving technology were also disscussed. It was suggested that the adoption of modern agriculture technology would be a short cut to the commercial application of phytoremediation to heavy metals.
