毛竹混交林植物种类组成的区域分布

对福建3个保护区分布的毛竹(Phyllostachys heterocycla cv．Pubescences)混交林群落植物种类的局域分布进行研究，结果表明，分布区内的3个毛竹混交林群落植物有445种，其中共有种14种、偏宜种56种、确限种375种．各群落植物主要由我国亚热带地区的地带性植物组成，集中在壳斗科(Fagaeeae)、杜鹃花科(Ericaceae)、茶科(Theaceae)、冬青科(Aquifoliaceae)、樟科(Lauraceae)和蔷薇科(Rosaceae)等几个科，但各群落之间种类成分存在着显著的差异．在3个毛竹混交林中，毛竹 长苞铁杉群落的生物量最大，但群落物种组成及结构与毛竹生物量关系不明显．

Local Distribution of Floristic Composition in the Mixed Forests of Phyllostachys heterocycla cv. Pubescences

This paper deals with local distribution of the plant species in the mixed forests of Phyllostachys (heterocycla.) pubescences communities distributed in three main natural reserves in Fujian. The results showed that there were 445 species in their distributing areas, among which there were 14 constant species, 56 selective species and 375 characteristic species. The plant species in each community were mainly composed of subtropical spcices, and their families were concentrated on Fagaceae, Ericaceae, Theaceae, Aquifoliaceae, Lauraceae and Rosaceae etc. , but distinctive difference of species composition also existed in each community. The biomass of Phyllostachys heterocycla+Tsuga longibracteata community is the greatest in the three communities, and the relationship of floristic composition, structure in the communities and the biomass of Phyllostachys heterocycla cv. Pubescences isn't obvious.
