采用样方调查法对福建省光泽县2个南方红豆杉群落(分别位于李坊乡杨里村后洋自然村、华桥乡古林村饶上自然村)的植物组成和多样性进行研究,结果表明:2个南方红豆杉群落共有维管束植物159种,隶属于127属76科,其中海拔480 m的后洋南方红豆杉群落中的常绿木本植物的物种数(60种)及其占总物种数的比例(59.41%)均大于海拔700 m的饶上南方红豆杉群落(57种、47.50%)。维管束植物热带分布属的数量在2个群落中均占优势,其百分比在后洋群落(63.29%)略高于饶上群落(57.78%),表明2个群落均具有明显的中亚热带森林植物区系特点。2个群落灌木层的植物多样性指数均高于其他层次,但南方红豆杉的幼苗幼树数量少,种群正处于衰退中。
The sample composition and diversity of two Taxus chinensis communities in Kwangze County of Fujian Province (Houyang Nature Village in Yangli Village, Lifang Township and Rao Shang Village in Gulin Village, Huaqiao Township) were studied by means of quadrat investigation. The results showed that: 2 There were 159 vascular plants belonging to 127 genera and 76 families in Taxus chinensis community, in which the species number (60 species) of evergreen woody plants and their percentage of total species (59.41%) were higher than the 700 m Raffia chinensis community (57 species, 47.50%). The number of genus of tropical vascular plants is dominant in both communities, and the percentage of them in later-marine communities (63.29%) is slightly higher than that in Rao Shang community (57.78%), indicating that both of the two communities have obvious subtropical forest plants Floristic characteristics The plant diversity index of shrub layer in two communities was higher than other levels, but the seedlings of southern yew was less in number and the population was in decline.
