Mining activities usually cause catastrophic an extensive environmental changes, an eventually cause major amages to the w hole ecosystem.The natural restoration for mine lan s an tailings is a very slow process, an even can har ly reach their original states.Therefore, how to evelop rapi an efficient approaches to accelerate restoration of mine lan s has been highlighte by restorationists an environmental engineers uring the past two eca es.Almost all stu ies in thisfiel in icate that the major problems come from soils:such as high metal concentrations, extremely strong aci ity resulting from oxi ation of pyrite, an poor fertility.Replacement of topsoil is therefore regar e as the most efficient metho to alleviate a verse con itions of substrates;if this metho is not available, other alternatives w ith lime, fertilizers, organic manures, garbage, mining wastes, an othersw ill be applicable.In the aspect of using plants, species with strong resistance an rapi grow th, like grasses an herbaceous legume
