摘　　要：通过对晋西黄土高原3个演替阶段煤矿废弃地的植被多样性的调查研究,探讨了煤矿废弃地植物群落形成与演替的规律,为煤矿废弃地植被生态恢复提供了参考依据。结果表明,垂头蒲公英(Taraxacum nutans Dahlst)、野艾蒿(Artemisia lavandulaefolia DC)、金色狗尾草(Setaria glauca(L.)Beauv)、高山蓼(Polygonum alpinum All)、牛筋草(Gramineae)等可在演替初期的煤矿废弃地上成功定居,成为这些植被中的优势种,可作为煤矿废弃地植被恢复治理的优先选用物种。随着煤矿废弃地演替时间的延长,植被具有由裸地依次向草丛、灌草丛、灌木林演替的趋势,植物物种多样性指数增加,群落的结构趋于稳定。Based on the biodiversity investigation in three successional stages of the abandoned coal mines in western Shanxi loess plateau, we detected the rules of the formation and succession of plant community, which provided a theoretical support for ecological restoration of abandoned coal mines. The results showed that Taraxaeum nutans Dahlst, Artemisia lavandulaefolia DC, Setaria glauca （L.）Beauv, Polygonum alpinum All and Gramineae can sue- cessfully settle in abandoned coal mines in early stage of succession as the dominant species in pant communities. Therefore, we infer that it can be used as the preferred species for vegetation restoration in abandoned coal mines. With increase of succession time, with the vegetation type turning from bare land to grass, shrub and tree, the plant diversity index increased and the community structure tends to be stable.
