中文摘要：

应用除趋势对应分析(DCA)与双向指示种分析(TWINSPAN)对濒危植物毛柄小勾儿茶(Berchemiella wilsoniivar.pubipetiolata)69块样地进行了排序与分类,共划分9个群落类型。结果表明,毛柄小勾儿茶生境特异性高。毛柄小勾儿茶在枫香(Liquidambar formosana)林、马尾松(Pinusmassoniana)+杉木(Cunninghamia lanceolata)+青冈栎(Quercus glauca)针阔混交林、杂木林和青榨槭(Acer davidii)+大果山胡椒(Lindera praecox)林中生长较好。这4个群落林下层优势种具有相似性:草本层的优势种中均有求米草(Oplismenus undulatifolius),常有三脉紫菀(Aster ageratoides);灌木层优势种常有大果山胡椒。毛柄小勾儿茶分布于海拔500~900 m的低山区,多分布于湿润、排水良好的沟谷边,生境坡向多为阴坡。

英文摘要：

By using DCA ordination and TWINSPAN classification,a total of 69 plots with endangered plant Berchemiella wilsonii var.pubipetiolata were partitioned into 9 community types.Both the methods of DCA ordination and TWINSPAN classification obtained very consistent results.B.wilsonii var.pubipetiolata had a high habitat speciality,and grew well in four communities,i.e.,Liquidambar formosana community,Pinus massoniana+Cunninghamia lanceolata+Quercus glauca confer and broadleaf mixed community,complex community,a...
