Abstract
Reviews were made on destruction of geological environment, heavy metal pollution of soil and water by exploitation of lead-zinc mine. Presentations were made on different plant species with potential hyper accumulation of heavy metal (such as Pb, Zn, Cr, Cu, Hg and As) for restoration of contaminated mining areas. Challenges of ecological restoration in lead-zinc mining areas were discussed. Countermeasures for phytoremediation of lead-zinc mining areas were proposed such as restoration with different site conditions, selection of ecological tree species, rational distribution of arbor-shrub-herb, improvement by transported soil.
