摘要
常绿阔叶林是亚热带地区占优势的植被类型。以往对亚热带常绿阔叶林的研究通常基于小尺度的研究,缺乏大尺度上的长期固定样地监测。本文基于江西阳际峰国家级自然保护区的25 hm2植被动态监测大样地,描述了该样地所属典型亚热带常绿阔叶林的群落结构特征。大样地内共记录到34 176个植株(DBH≥2 cm),这些植株分属于49科65属115种。按物种重要值排序,大样地内优势木本植物种(重要值大于2.0)的8个种为:米槠(Castanopsis carlesii)、樟树(Cinnamomum camphora)、甜槠(Castanopsis eyrei)、木荷(Schima superba)、山杜英(Elaeocarpus sylvestris)、虎皮楠(Daphniphyllum oldhami)、浙江楠(Phoebe chekiangensis)、山苍子(Litsea cubeba)。植株径级分布呈明显的倒"J"形。
Subtropical evergreen broad-leaved forest is the most dominant vegetation type. However, most studies on subtropical evergreen broad-leaved forest have been conducted at relatively small spatial scales, as large-scale permanent plots are scarce. In the study, we described the community structure characteristics of one 25 hm^2 plot established in the subtropical evergreen broad-leaved forest of Yangjifeng nation nature reserve, Jiangxi Province. A total of 34 176 plants were recorded in details（DBH ≥2 cm）, which belonging to 65 species, 65 genera and 49 families. Castanopsis carlesii,Cinnamomum camphora, Castanopsis eyrei, Schima superba, Elaeocarpus sylvestris, Daphniphyllum oldhami, Phoebe chekiangensis, Litsea cubeba are the most dominant woody species with importance values greater than 2.0. The DBH size class distribution is a typical inverse-J distribution.
