| 摘 要： | 通过样地调查，对浙江百山祖自然保护区五岭坑低山常绿阔叶林群落的物种组成、群落结构、物种多样性进行研究。结果表明:1)群落内物种丰富，计33科58属124种，种类组成以冬青科、樟科、壳斗科、山茶科、蔷薇科、山矾科等为主，常绿阔叶树种104种3 040株，分别占种数和总株数的83.87%、98.51%，群落的树种组成反映了中亚热带常绿阔叶林植被的典型特征；2)群落幼树量大,自然更新良好。胸径与株数呈指数分布,立木径级分布连续,表明该群落处于成熟阶段。群落的平均胸径与密度之间存在负相关性；3)群落的Simpson指数、Gini均匀度指数、Pielou均匀度指数均较高，说明树种丰富，分布均匀,优势种不明显。

| Abstract: | In order to understand the floristic composition, community structure and species diversity of an evergreen broad-leaved forest in the low-mountain of Baishanzu National Nature Reserve,6 typical plots with 30 meters in length and 30 meters in width were established and the vegetations of these plots were surveyed by adjacent lattice method.Major results demonstrated that:1) the community was rich in plant species,124 species were found,belonging 33 families and 58 genera,dominated by Aquifoliaceae,Lauraceae,Fagaceae,Theaceae,Rosaceae,Symplocaceae and so on.The number of evergreen broad-leaved trees in the community was 3 040,accounting for 98.51% of the total tree number in the community,and the number of plant species was 104,accounting for 83.87%,reflecting the typical characteristics of vegetation in subtropical evergreen broad-leaved forest.2) A lot of saplings exhibited good natural regeneration.Distribution of the diameter at breast height (DBH) was detected as exponential distribution,which indicated the DBH distribution of standing trees was continuous and the community was at the mature stage.There was a negative correlation between the average DBH and density of the trees in the community.3) In the aspect of species diversity indices,the species was abundant and evenly distributed,but the dominant species was not obvious. |
