对福建、广东、广西、贵州和湖南分布的长苞铁杉 ( Tsuga longibracteata)群落主要木本植物种类的局域分布进行研究 .结果表明 ,分布区内的 7个长苞铁杉群落木本植物有 1 68种 ;组成上除长苞铁杉外 ,仅福建省的天宝岩、梅花山和大丰山长苞铁杉群落共有种为甜槠 ( Castanop-sis eyrei)、木荷 ( Schima superba)和深山含笑 ( Michelia maudiae) ;各群落物种种数在前几位的科具有很大的相似性 ,集中在壳斗科 ( Fagaceae)、杜鹃花科 ( Ericaceae)、山茶科 ( Theaceae)和樟科( Lauraceae)等少数几个科 ;整个分布区内除长苞铁杉外没有共有种 ,群落与群落之间的偏宜种有 33种 ,群落的特征种共有 1 34种 .
The distribution of main woody plant species in Tsuga longibracteata communities distributed in Fujian, Guangdong, Guangxi, Guizhou and Hunan was studied.The results showed that the seven woody plants There were 688 species of Castanopsis sylvestris, Castanea sis eyrei, Schima superba, only the species of Tian Bao Yan, Mei Hua Shan and Dafeng Shan in Heilongjiang Province, And Michelia maudiae (Michelia maudiae). The families with the highest number of species in each community have great similarities in the families Fagaceae, Ericaceae, Theaceae and Lauraceae (Lauraceae) and so on. There were no common species in the whole distribution area except for the species of Tsuga crassipes.
