Abstract
Multi-metal pollution in mine and surrounding area has become one of the most serious environmental problems. The research progress and field practice of phytoremediation of multi-metal contaminated soil were introduced in this paper. On the grounds of the domestic and overseas research trends of the remediation technology and mechanism, key issues on current research as well as the future study on remediation of multi-metal polluted soil were discussed. This paper also pointed out that mechanism study and system establishment for plant-microbe-chemistry integrated remediation technology (based on phytoextraction and phytostabilization respectively)was imperatively needed in view of the diverse characteristics of heavy metal contaminated soils in mine and surrounding area.
