摘  要:
【目的】了解黄山水榆花楸群落特征,为其资源保护和开发利用提供依据。【方法】通过典型群落样方调查,对其物种组成、群落结构进行统计与分析。【结果】1该群落在3 200 m2的样地内共有维管束植物132种,隶属于54科98属;2重要值分析表明,黄山松和华箬竹在乔木层和灌木层占有较明显的优势,分别为21.47%和26.99%;3植物群落区系中属分布类型有11种,以北温带成分为主,世界分布、泛热带和东亚成分占一定比例,表现出较为明显的过渡性质;4群落内植物生活型以高位芽植物最多,为52种,其次是地上芽植物与地面芽植物;5按Raunkiaer的划分标准将种群频度划为5个等级,其分布规律为A>B>CE,优势种植物分布不均匀,群落有被分化和演替的趋势;6立木级分析表明,水榆花楸种群结构呈纺锤型,有衰退的迹象。【结论】黄山水榆花楸群落物种丰富,灌木层种间竞争激烈;如果水榆花楸种群没有足够的更新幼苗补充,它将会退出当前的群落。

摘  要:
【Objective】The aim of this paper was to understand the structure of Sorbus alnifolia in Huangshan and to provide a basis for its protection and development.【Method】Species composition and community structure of S. alnifolia was analyzed by typical sampling plot method. 【Results】1There were 132 vascular plants,which belonged to 98 genera and 87 families in the 3 200 m2 quadrats;2Important value analysis showed that Pinus taiwanensis and Sasa sinica in the tree layer and shrub layer were more dominant,with a coverage of 21.47% and 26.99%,respectively;3The genera of community flora could be divided into 11 distribution types and north temperate zone plate as the main component. The world distribution Pantropic and East asian element assume a definite proportion and the plant flora had evidently characteristics of transition;4Phanerophytes(52 species of plants)were dominant in the life-form,followed by chamaephytes and hemicryptophytes;5According to the analyses of Raunkiaer frequency law,species abundance pattern was vided into five grades(A>B>CE). 6The species were uneven distribution in the community. 【Conclusion】The species in Sorbus alnifolia community of Huangshan was abundant. The competition of shrub layer was fierce. If there was no sufficient regeneration seedlings,S. alnifolia would be degraded.
