| Abstract: | In this paper the hyperaccumulative property and superiority of weeds in the remediation of soils contaminated by heavy metals are revied.With the properties of strong endurance to adverse environment,fast growing and high reproduction,especially the characteristics of the fast increasing in biomass under feasible environmental factors,weed can make effective the defect and cover the shortage of the remediation available by plants,so it is a kind of ideal remediative resource.The comparison among weed and other hyperaccumulators and the superiority of weed are also discussed.It was suggested that the comprehensive utilization of plant resource would make a great progress in the remediation of soils contaminated by heavy metals. |
