摘　　要：为探讨不同废弃年限的矿区植被恢复过程中植物群落特征,对太原东山地区废弃煤矿区的植被进行了实地调查。结果表明,在所调查的10个废弃矿区的205个样方中共有高等植物121种,分属于43科86属,其中,菊科11属20种,豆科7属18种,禾本科12属15种,3个科合计30属53种,占全部种数的43.80%。表明3个科的植物在东山矿区植被的自然恢复演替过程中所起的作用最大,在该地区的植物区系中占据着重要地位。To explore the characteristics of plant communities in the process of vegetation restoration in mining areas with different abandoned years,the vegetation of abandoned coal mines in Dongshan area of Taiyuan city was investigated.The results showed that121 species of higher plants,belonging to 43 families and 86 genera,were found in 205 plots of 10 abandoned mining areas,including20 species of 11 genera of Compositae,18 species of 7 genera of Leguminosae,15 species of 12 genera of Gramineae,30 genera and 53 species of three families accounted for 43.80%of the total species.Therefore,it is concluded that the three families play a dominant role in the natural restoration and vegetation succession in the mining areas of Dongshan,and they also play an important role in the flora of the area.
