植物修复重金属污染土壤的强化措施

植物修复技术作为一种新兴的绿色环保技术,有着高效、经济和生态协调等特点而成为当前研究的热点领域,而且由于其修复的彻底性和环境友好性而在治理污染土壤实地过程得到广泛应用.概述了当前植物修复研究的基本类型和修复机理,并着重从生物技术、农艺措施和物理化学等强化手段上阐述了利用超富集植物修复污染土壤,以进一步提高超富集植物的修复效率,为大规模治理重金属污染土壤和商业化应用提供技术途径和科学依据.

Phytoremediation and strengthening measures for soil contaminated by heavy metals

Phytoremediation has been regarded as a suitable technique for the pollution control of heavymetal contaminated soil for green, safe technology and the properties of efficiency, economy and ecological harmony. And it has been applied widely on the spot for polluted soil for its thorough remediation and environmentfriendly alternative. After a short introduction to the principles and types of phytormediation,this review focused on strengthening methods including biotechnology, agricultural technology, physical and chemical technology. Multi-channel approaches should be taken to make pbytoremediation and engineering available, field survey at more place to try to research for more tolerant and accumulating plants which may provide for the breakthrough of phytoremediation technique. This provided novel approaches to restore the heavy metal polluted soil using efficient remediation techniques. It offered technique route and scientific basis for commercial application and remediation of contaminated soil on a large scale.
