摘    要:不同地区的3个长苞铁杉群落的植物种类较多,有蕨类植物,裸子植物,双子叶植物,单子叶植物,以双子叶植物种类占绝对优势,但群落相似性较低,3个群落共同出现的科,属,种占全部科,属,种比例依次为24.14%,13.22%,3.94%,区系特征上,3个群落分属于11个分布区类型,以热带分布类型属为主;随海拔上升,3个群落热带分布类型属的比例依次下降。

关 键 词:长苞铁杉群落  植物组成  区系

Abstract:There were ferns, gymnosperms, dicotyledons and monocotyledons in all the three Tsuga longibracteata communities of local distribution with dicotyledons dominant absolutely. The similarity of floristic composition among the communities is low, and the proportions of constant families, constant genera and constant species are 24.14%, 13.22%, 3.94% in turn. About the characters of flora, all the three communities belong to 11 distributional types, mostly are tropical distribution types. However, with the rise of elevation, the genus proportion of tropical distribution type in the floristic composition descend.
Keywords:Tsuga longibracteata community  floristic composition  flora  local distribution
