芦苇修复重金属污染土壤研究进展

Research Progress of Remedying the Heavy Metal Contaminated Soils With Phragmites communis

土壤重金属污染已成为世界性的环境问题,利用植物修复重金属污染土壤是当前环境修复研究的热点,近年来,国内外众多学者相继开展了植物修复重金属污染土壤的研究,报道了一系列重要研究成果,芦苇对重金属具有较强的耐受及吸收能力,综述了芦苇对重金属的吸收及重金属在芦苇体内的分布特征,重金属对芦苇的毒害及芦苇对重金属的解毒机制,芦苇在土壤重金属污染修复中的强化途径,并对芦苇修复重金属污染土壤研究前景进行了讨论。

Remediation of heavy metals had become a global environmental problem,Phytoremediation was a hot current study.In recent years,many scholars have carried out studies of heavy metal contaminated soil phytoremediation.It reported a series of important research results,Phragmites communis had a strong tolerance and absorption capacity of heavy metals.This study reviewed accumulation and distribution of heavy metals in Phragmites communis,heavy metal poisoning and heavy metal detoxification mechanism of Phragmites communis,and intensive way.Heavy metal contaminated soil by Phragmites communis′s outlook be discussed.
