摘    要:植物修复技术是近年来发展起来的一种主要用于清除土壤重金属污染的生态技术.重金属超积累植物及植物修复技术是当前国内外学术界研究的热点领域之一.植物修复重金属污染的机制主要是植物对污染物的吸收、累积和转化,具有成本低、不破坏土壤和河流生态环境、不引起二次污染等优点.综述了近十几年来国内外植物修复重金属污染的现状及超积累植物机理,探讨植物修复技术目前尚存在的某些不足及今后努力的方向.

关 键 词:土壤重金属污染  植物修复  超积累植物  重金属污染土壤  植物修复  超积累植物  研究进展  Research  Advance  Soils  Heavy  Metal  方向  存在  技术目  机理  现状  二次污染  河流生态环境  破坏  成本  转化  吸收  污染物  机制

Abstract:Phytoremediation is an ecological technique used to clean polluted soils by heavy metals. The study on phytoremediation and hyperaccumulator is one of the hot fields of academic research worldwide. The mechanism of phytoremediation for soil polluted by heavy metals is that plants absorb, accumulate and translate pollutants. Phytoremediation has many advantages such as low cost, no worsening the ecological environment of soils and rivers and no recontamination. Reviewed the actuality of phytoremediation of soil polluted by heavy metal and the study of mechanism on hyper - accumulator in past ten years, and discussed some shortage of the technology still exist currently on phytoremediation and direction of development.
Keywords:heavy metals contaminated soil  phytoremediation  hyperaccumulator
