摘　　要：对太行山南麓的23个栓皮栎群落的物种组成、群落结构、物种多样性以及土壤状况进行了初步调查研究,结果表明,在太行山南麓栓皮栎林群落中共有维管束植物89种,分属37科78属.生活型谱以高位芽植物最多.群落空间结构特征表明,该地区栓皮栎群落成层现象非常明显,分为乔木层、灌木层和草本层.乔木层物种多样性指数不高,群落物种丰富度和多样性指数主要受灌木层和草本层影响.群落的物种丰富度、物种多样性指数反映出基本一致的趋势,不同层次的Shannon-W iener多样性指数和S impson多样性指数的趋势是草本层>灌木层>乔木层.群落土壤呈弱碱性,土壤中速效氮、速效钾及阳离子交换量与有机质均呈极显著性正相关,且随着土壤深度的增加而减少.Based on the data from 23 sample Quercus variabilis forests community plots in the south area of Taihang Mountains, community composition, community structures, and species diversity of Quercus variabilis forests and soil conditions were studied in this area. The results showed there are 37 families,78 genera and 89 species in the community. Phanerophytes are the largest in all species. The characteristics of community space structures showed the layered phenomena is very obvious of Quercus variabilis forests in the area, which can be divided into arborous layer, shrub layer, and herbaceous layer. The arborous layer＇ s species diversity index is low, community species richness and species diversity index are mostly influenced by shrub layer and herbaceous layer. The community species richness and species diversity index reflect accordant trend. Among the two layers, the Shannon -Wiener index, Simpson index showed herbaceous layer 〉 shrub layer 〉 arborous layer. Soil in the community presents alkalescence, and the soluble N,soluble K and cation exchange in the soil are positively correlative to organic matter prominently, which are decreasing with the depth of the soil increasing.
