摘　　要：Deficiency of nutrients and the role of legume species in restoration of mined wastelands are reviewed in this paper.The deficiency of major nutrients,especially poverty of nitrogen,is one of the most important limiting factors for vegetation restoration of mining wastelands.Legume species are very useful in restoration of wasteland because N-fixing properties of legume can increase the accumulation of nitrogen and organic matter.Effects of edaphic conditions,especially heavy metal toxicity on N-fixing of rhizobia-legume symbiotic,selection for tolerant legume species and application of those species on restoration of mining wastelands were also discussed.Deficiency of nutrients and the role of legume species in restoration of mined wastelands are reviewed in this paper.The deficiency of major nutrients,especially poverty of nitrogen,is one of the most important limiting factors for vegetation restoration of mining wastelands.Legume species are very useful in restoration of wasteland because N-fixing properties of legume can increase the accumulation of nitrogen and organic matter.Effects of edaphic conditions,especially heavy metal toxicity on N-fixing of rhizobia-legume symbiotic,selection for tolerant legume species and application of those species on restoration of mining wastelands were also discussed.
