Abstract:In order to explore the ability to resist heavy metal pollution and potential of ecological restoration of three herbage, such as Thysanolaena latifolia, Neyraudia reynaudiana and Miscanthus sinensis, their physiological indexes and heavy metal contents grown in lead-cadmium contaminated soil were measured. The results showed that POD activity and Pro content of three plants were in the order of M. sinensis > N. reynaudiana > T. latifolia under the same pollution level, while MDA content was M. sinensis > T. latifolia > N. reynaudiana. Lead (Pb) and cadmium (Cd) contents in M. sinensis were the highest among three species with the biggest bio-accumulating coefficient. The resistant capability to heavy metals was in the order of M. sinensis > N. reynaudiana > T. latifolia. Therefore, Miscanthus sinensis could be used as an alternative plant for vegetation restoration in mining areas.
