| 摘 要： | 以安太堡露天煤矿生态复垦区0.8 hm2刺槐+油松混交林样地为研究平台,基于样地内320个1 m×1 m草本样方的调查数据,对复垦17年后草本层的物种组成、基本数量特征和空间分布等进行研究.结果表明:样地内草本层物种组成丰富,共调查到44种植物,隶属于16科30属,其中禾本科和菊科为优势科,黄花蒿、披碱草和大籽蒿为优势种,初期种植种无芒雀麦等退化严重;重要值、多度和频度在各科和各种之间差值较大;优势科和优势种分布广泛,但物种分布呈现出明显的空间异质性.

| Abstract: | A patch of open coal mining land was reclaimed for ecological rehabitation 17 years ago in Antaibao,Shanxi Province,China.Under the rehabilitated Robinia pseudoacacia + Pinus tabuliformis mixed forest,herbacious plants in 320 quadrats(1 m × 1 m) in the 0.8 hm2 plot were surveyed for the species composition,spatial patterns and other community properties.The results showed that the land was rich in herbaceous species,containing 44 species,which belonged to 30 genera under 16 families.The dominant families were Poaceae and Asteraceae,and the dominant species included Artemisia annua,Elymus dahuricus and Artemisia sieversiana.The initially planted Bromus inermis deteriorated badly.The important value,species abundance and frequencies were different among the families or species.The dominant families and species were commonly distributed,and the spatial patterns were obviously spatial heterogeneous |
