摘要
概括了中国土壤重金属污染现状以及危害,总结了土壤重金属污染的植物修复类型和优缺点,超富集植物的研究进展重点阐述了植物对土壤重金属耐性和富集机制,以及超富集植物的种质资源,最后指出了植物修复未来的研究趋势。
This paper generalized the current situation of soil heavy metal pollution and its increasing harm to the environment in China,and also summarized the contaminated phytoremediation types and their advantages and disadvantages.In terms of the research progress of hyperaccumulators,this paper proposed germplasm resources of hyperaccumulators in some common soil contamination （copper,nickel,lead,zinc,cadmium） and expounded the tolerance and concentration mechanism of the plants to heavy metal.Lastly,this paper indicated the future research direction and development trend of the phytoremediation technology by means of the discussion on the limitations of phytoremediation technology.
