重金属污染土壤的植物修复技术研究

植物修复重金属污染土壤已经成为当今科学家研究的热点问题。国内研究者已发表众多重金属污染土壤修复技术的文献综述，但单纯对重金属污染土壤的植物修复技术、特别是植物收获后的处置技术的系统综合的文献综述少之又少。为此，系统阐述了植物修复技术的内涵、组成部分、优缺点、超富集植物的概念、研究概况和修复植物收获后的处置技术，指出植物采矿技术可能成为科学家们下一步研究的重点，并对植物修复技术发展未来进行了展望。

Research on Phytoremediation of Soil Contaminated by Heavy Metals

Phytoremediation is a technique using plants to remediation heavy metal contaminants from soils has become a topic problem in current research. Domestic researchers have published a number of literature review about remediation technologies of soil contaminated by heavy metals, but the comprehensive literature review that simply phytoremediation for heavy metal contaminated soil, especially plants after harvest disposal technology is very few. We reviewed the connotation, composition, the advantages and disadvantages of phytoremediation, the concept, research overview about hyperaccumulator and technique for disposal of phytoremediting plants after harvest, indicate that the plant mining technology may become the focus of further research of the scientists ,and phytoremediation technology development prospects in the future.
