土壤重金属污染的植物修复研究现状与发展前景

Research Advances and Development Prospect of Phytoremediation in Heavy Metal Contamination Soil

重金属污染是土壤污染中危害极大的一类,重金属污染的防治及其修复是目前国际上研究的热点之一。综述了土壤重金属污染及其植物修复的方法,概述了超富集植物的概念、植物修复的机制和方式,系统阐述植物修复的应用前景和今后的研究方向。

Heavy metal contamination is extremely harmful in soil contamination, It is one of the research priorities in the world to control and remedy heavy metal contamination, Heavy metal contamination in soil and its phytoremediation are reviewed in this paper. At the same time, the definition of hyper-accumulated plants and the mechanism and measures of phytoremediation are described in detail. The perspectives in research and application of phytoremediation were expounded systematically.
