摘　　要：对于土壤中积累的大量有毒有害物质,尤其是重金属污染物,由于其对人类具有潜在的威胁,已经越来越多地引起了人们的关注。目前,处理重金属污染主要是一些物理化学方法,它们虽各有优点,但不同程度地存在投资费用高、操作运行难、易产生2次污染等缺点。近年来出现的植物修复则可以满足这一需要,尽管植物修复会受到植物种类、植物根系分布、污染物种类等影响,但已有研究表明,与传统的处理技术相比,该技术在环境保护中具有重要的理论价值和广阔的实用前景。The soil pollution has been the one of the serious environmental problems with the rapid development of the industry and the growth of the world population nowadays all over the world. A large number of harmful substances in the contaminated soil, especially the heavy metal pollutant which has potential threat to the mankind, have been paid attention by many people increasingly. At present, there are mainly some physical chemistry methods to deal with the heavy metal pollutant in the world, but they have some disadvantages, such as high cost, hard-operating, secondary pollution, etc. Although phytoremediation is limited by species of plants, rhizosphere and the dements of the pollutant, some research has indicated the theory have wide practical prospect in environmental protection in the future. Researches of phytoremedition to get rid of heavy metal in the contaminated soil were reviewed in the paper.
