摘要：季风常绿阔叶林是我国南亚热带典型的地带性植被,建立森林动态监测样地是研究生物多样性维持和群落构建机制的重要平台。该文以普洱30 hm^2森林动态监测样地为研究对象,采用多元回归树、重要值、主成分分析与指示种相结合的方法对样地内750个样方进行群丛数量分类,以获取季风常绿阔叶林森林植被群丛类型。结果表明:森林动态监测样地共发现木本植物271种,隶属于78科178属,群落类型为短刺锥(Castanopsis echidnocarpta)群系,可划分4个群丛类型,分别是珍珠花+毛银柴-短刺锥+泥柯群丛(Lyonia ovalifolia+Aporosa villosa-Castanopsis echidnocarpa+Lithocarpus fenestratus Association)、云南瘿椒树+耳叶柯-短刺锥+西南木荷群丛(Tapiscia yunnanensis+Lithocarpus grandifolius-Castanopsis echidnocarpa+Schima wallichii Association)、大果杜英+黄药大头茶-短刺锥+西南木荷群丛(Elaeocarpus sikkimensis+Polyspora chrysandraCastanopsis echidnocarpa+Schima wallichii Association)、西桦+尼泊尔桤木-短刺锥+枹丝锥群丛(Betula alnoides+Alnus nepalensis-Castanopsis echidnocarpa+Castanopsis calathiformis Association)。群丛间物种分布存在较多过渡重叠,指示物种是区分群丛类型的主要依据,海拔与坡向对群丛分类有较大的影响,坡度对群丛分类影响较小。
Aims The monsoon broad-leaved evergreen forest is a typical zonal vegetation of south subtropical China,where forest dynamics plot is a study platform of mechanisms of biodiversity maintenance and community assembly.Our objectives were to obtain plant association types in a 30 hm^2 forest dynamic monitoring plot in the Pu’er City,Yunnan Province.Methods We identified typical association types by the methods of multivariate regression trees,importance value,principal component analysis and indicator species based on 750 subplots(20 m×20 m),and analyzed the differences of topography factors and community characteristics among different plant associations.Important findings The results showed that the specie richness of woody species(diameter at breast height(DBH)≥1 cm)was 271,which belonged to 78 families and 178 genera in the forest dynamic plot.The community formation was Formation Castanopsis echidnocarpa.Forest was divided into four associations:(1)Lyonia ovalifolia+Aporosa villosa-Castanopsis echidnocarpa+Lithocarpus fenestratus Association,(2)Tapiscia yunnanensis+Lithocarpus grandifolius-Castanopsis echidnocarp+Schima wallichii Association,(3)Elaeocarpus sikkimensis+Polyspora chrysandra-Castanopsis echidnocarp+Schima wallichii Association,and(4)Betula alnoides+Alnus nepalensis-Castanopsis echidnocarp+Castanopsis calathiformis Association.There were many transitional overlaps in the distribution of associations,while indicator species was the main reference for distinguishing the types of associations.In addition,altitude and slope aspect had a great influence on the plant association types,while slope per se had a relatively weak impact on the association types.
