摘要
对老君山国家级自然保护区的油松林采用样地法调查其林下植被的谱系结构及其多样性.结果表明:不常见的物种的谱系结构的枝长较长且与其他物种间的亲缘关系较疏远;而常见物种的枝长较短且与其他物种间的亲缘关系相对较近;其林下植被的谱系亲缘关系较疏远是竞争排斥主导群落构建的结果.
Abstract
A plot was setup in the Pinus tabulaeformis forest in the Laojunshan National Nature Reserve,to survey the phylogenetic structure understory vegetation.The results showed that:In the understory vegetation,species with longer branches in the phylogenetic structure and distant relationships with other species are generally rare species;while those with shorter branches and relatively close relationships with other species are generally more.The far lineage relationship of understory vegetation of P.tabulaeformis is the result of competition and exclusion.
