我国农田土壤重金属污染的植物修复技术现状与展望

摘要

The phenomenon of farmland soil heavy metal pollution is increasingly serious in our country, repairing has already been to be imperative. Compared with engineering remediation, physics and chemical remediation technology, Phytoremediation is low cost, wide application range, so it becomes one of widespread attention heavy metal contaminated soil remediation technology. This paper briefly describes the present situation of the farmland soil heavy metal pol ution in our country, introduces the development situation of the phytoremediation and hyperaccumulator plants, also forecasts the future development trend.%我国农田土壤重金属污染现象日益严重，修复已经势在必行。植物修复技术与工程修复和物理、化学修复技术相比，成本低，适用范围广，成为受到广泛重视的土壤重金属污染修复技术之一。本文简述了我国农田土壤重金属污染现状，介绍了植物修复技术与超富集植物现阶段在国内的发展应用状况，并对其未来发展趋势进行展望。
