摘　　要：采用样地法调查老君山自然保护区麻栎林的林下植被的谱系结构及其谱系多样性。结果表明:谱系结构的枝长较长且与其他物种间的亲缘关系较远的种类通常少见;而枝长较短且与其他物种间的亲缘关系相对较近的种类通常较多见,且多为优势种或主要伴生种。麻栎林林下植被较接近的谱系亲缘关系是生境过滤主导群落构建的结果。A plot was setup in Quercusacutissimaforest in the Laojunshan National Nature Reserve,to survey the phylogenetic structure and phylogenetic diversity of understory vegetation.The results showed that:In the shrub layer and herbaceous layer,species with longer branches in the phylogenetic structure and distant relationships with other species are generally rare;while those with shorter branches and relatively close relationships with other species are generally more,and always are dominant or main associated species.The close phylogenetic relationship of understory vegetation of Q.acutissimaforest is the result of habitat filtering.

关 键 词：谱系结构 谱系多样性 林下植被 河南老君山自然保护区
