Abstract: Facing the severe strategy of the heavy metal contaminated soils, there has appeared some kinds of remedy technology for contaminated soils. The traditional and the modern techniques have theirs advantedges and disadvantedges. Through the practicing, the phytoremediation has been regarded as suitable technique for the sustainable method of the pollution control of heavy metals contaminated soils than the traditional techniques. After introduction the chief mechanisms of phytoremediation , the directions of efficient improvement of phytoremediationare discussed.
