摘    要:以大黑山水土保持生态修复工程示范区为研究区域,运用典型植物群落物种组成和群落物种多样性指数方法,对大黑山水土保持生态修复区典型植物群落物种多样性变化特征进行了研究,结果表明,生态修复区内天然次生林植物群落形成了乔灌草相结合的稳定的植物群落结构。人工林植物群落按生长型可以划为明显的乔木层和草本层2层群落结构类型;典型植物群落物种多样性指数的排序为:蒙古栎+蒙椴植物群落(Ⅱ)>山杏+黄榆植物群落(Ⅰ)>蒙古栎植物群落(Ⅲ)>油松+山杏混交植物群落(Ⅴ)>油松纯林植物群落(Ⅳ)>油松+沙棘混交植物群落(Ⅵ)>油松疏林植物群落(Ⅶ)。天然次生林植物群落的物种多样性要大于人工林植物群落。天然次生林植物群落由于远离人类活动区,长期以来受人为干扰较小,逐渐形成了相对比较发达的草本层植物群落。

关 键 词:生态修复  典型植被类型  物种多样性  变化特征

Abstract:Taking Daheishan soil and water conservation & ecological restoration engineering demonstration area as study area,using species composition of typical plant community and community diversity index method,variation characteristics of species diversity for typical plant community of Daheishan soil and water conservation & ecological restoration area were studied;result shows that :in natural secondary forest of ecological restoration areas,stable plant community structure of combination of tall tree,shrub and grass was formed.Plantation plant community by growth type were divided into two layers(tree and herbaceous layers) community structure types;the order of species diversity indices of typical plant community is:Quercus mongolica + Tilia mongolica plant communities(Ⅱ) > Prunus armeniaca + Ulmus macrocarpa plant communities(Ⅰ)> Quercus mongolica plant communities(Ⅲ)> Pinus tabulaeformis + Prunus armeniaca mixed-plant communities(Ⅴ)> pure forest of P.tabulaeformis plant communities(Ⅳ)> P.tabulaeformis+ Hippophae rhamnoides mixed-plant communities(Ⅵ)>P.tabulaeformis sparse forest plant communities(Ⅶ).Species diversity of natural secondary forest communities is greater than that of the plantations.Due to away from human activity,plant communities of natural secondary forest,which is lightly disturbed by artificial factor for a long time,gradually formed a relatively well-developed herbaceous layer plant communities.
Keywords:ecological restoration  typical vegetation types  species diversity  variation characteristics
