| 摘 要： | 矿业废弃地是指因采矿活动所破坏的 ,非经治理而无法使用的土地[9] 。矿业废弃地植被恢复的最重要的限制因子之一是重金属毒性和养分不足 ,而Ｎ素的极端不足又是养分不足中的核心问题[8,14 ] 。因此 ,在矿业废弃地植被化过程中如何促进废弃地养分循环和营养元素的累积 ,包括利用豆科植物根瘤菌共生体的固氮作用来加速废弃地有机质及Ｎ素的积累 ,一直是废弃地植被恢复研究和实践中的热点问题之一[10 ] 。1 矿业废弃地的养分1.1 矿业废弃地的养分状况矿业废弃地的基质 ,是一些与一般土壤有着显著区别的所谓矿山土 ,它是采矿业等产生的固体废…

| Abstract: | 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. |
