植物修复土壤重金属污染的研究进展

Progress of Phytoremediation on Soil Polluted by Heavy Metal

植物修复技术被认为是治理重金属污染最为绿色的方法,因为此技术成本低、实施方便、无污染。超富集植物的研究是重金属污染植物修复的重点,然而一种植物由具有富集重金属特性到应用于现实的重金属污染修复并非易事。研究表明,在现实条件下,植物修复技术应用于治理土壤重金属污染中存在一些约束。本文系统地总结了目前超富集植物的研究方法和研究现状,通过分析超富集植物在现实条件下修复土壤重金属污染的不足,提出土壤重金属污染植物修复的方向。

Phytoremediation is considered to be the most green way to control heavy-metal pollution,because the technology is low cost,easy to implement,and non-polluting.Hyperaccumulator applied in phytoremediation is the focus of remediation of heavy-metal pollution,but applyinging the heavy-metal enrichment plant in the reality is not easy.A lot of research found that,under realistic conditions,there are some constraints on phytoremediation of soils polluted by heavy.We summarizes the studying methods and current status in hyperaccumulator.By analyzing the shortcomings on remediation on soils polluted by heavy metal by under realistic conditions,we provided the studying direction on phytoremediation of soils contaminated by heavy metal.
