摘要/Abstract

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 wilsonii var.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(Pinus massoniana)＋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。

Abstract: 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,and Acer davidii+Lindera praecox community.The understory of the four communities had some evident similarities,i.e.,Oplismenus undulatifolius and Aster ageratoides were the two dominant species of herb layer,and L.praecox was one of the dominant species of shrub layerB.wilsonii var.pubipetiolatamostly distributed in low altitude (500-900 m above sea level) mountainous region characterized by higher humidity and well drainage,and was mostly found at northern slopes.
