摘要
重金属土壤污染是我国亟待解决的环境问题之一。文章在概述土壤重金属污染的特点、现状的基础上,系统了总结了土壤重金属污染修复现状,着重阐述了植物-微生物联合对土壤重金属的固定/活化作用机制,并且介绍了微生物在联合修复中对重金属超累积植物的促生作用,最后对植物-微生物联合修复土壤重金属污染存在的问题进行了总结和展望,以期为我国重金属污染土壤的修复以及该领域的深层次研究提供参考。
Heavy metals contaminated soil is one of the environmental problems that need to be solved urgently in our country. Based on the overview of the characteristics and the status quo of soil heavy metal pollution, the remediation measures of heavy metal pollution in soil was summarized systematically, and emphatically focuses on mechanism of plant-associated microbes immobilization/activation heavy metals in soil, and the hyper accumulator plant growth promoting effect of microorganisms in remediation of heavy metals was introduced synchronously. Finally, in order to provide reference for the remediation of heavy metals contaminated soil in our country and in the field of deep research, the existence of heavy metals pollution remediation of soil plant-associated microbes problems are summarized and discussed.
