摘要: 在神农架锐齿槲栎集中分布地带布设20个样方,对其进行植物物种及群落调查,分析其植物物种组成、区系地理成分和群落特征。结果表明:锐齿槲栎林群落中共出现维管束植物199种,隶属于71科145属,物种组成主要以蔷薇科、菊科和忍冬科等植物为主。区系组成中,在科的层次上,以世界广布科占优势,其次为泛热带分布科; 属的分布以温带分布属类型为优势,占总属数的50.3%,具有明显温带性质,同时也具有一定的热带成分。运用二元指示种分析(TWINSPAN)方法,可将神农架锐齿槲栎林划分为7个群落类型,并以锐齿槲栎+四照花-绿叶胡枝子-中日金星蕨群丛和锐齿槲栎+华山松-鄂西绣线菊-苔草群丛类型最为常见。

Abstract: The plant species composition, plant flora and community characteristics of Quercus aliena var. acutiserrata forests were analyzed based on investigation of 20 plots established in the concentrated distribution area of Q. aliena var. acutiserrata in Shennongjia area of China. The results showed that the Q. aliena var. acutiserrata communities was consisted of 199 species of vascular plants, which belonged to 145 genera in 71 families. Species from Rosaceae, Compositae and Caprifoliaceae took a more dominant position in these communities. In floristic composition, the widespread family was dominant, followed by pantropic family. On the genus level, the temperate composition was dominant accounting for 50.3% of the total number of genera, and there was also certain tropical composition. The forests of Q. aliena var. acutiserrata could be divided into 7 community types according to the results of TWINSPAN assessment. Quercus aliena var. acutiserrata+Dendrobenthamia japonica var. chinensis-Lespedeza buergeri-Parathelypteris nipponica and Quercus aliena var. acutiserrata+Pinus armandii-Spiraea veitchii-Carex ssp. were the most common species.
