摘 要：
The concepts,principles,main methods and existing problems of phytoextraction(mainly chelate-induced phytoremediation) of heavy metal contaminated soil were reviewed.Phytoremediation is the process to use green plants to remove pollutants from the environment or to transform the pollutants into harmless forms,also known as plants-bioremediation.lt includes phytoextraction,phytofiltration or rhizofiltration,phytovolatilization,phytostabilization and phytodegradation.Phytoextraction,which has a low cost and is able to maintain soil fertility,has been paid more and more attention recently.
