摘要： 浙江九龙山国家级自然保护区中山地带保存着我国中亚热带地区罕见的大面积原生常绿阔叶林, 其群落结构完整, 具有极高的典型性与代表性, 是研究中山地带森林群落组成与结构的理想区域。依据中国森林生物多样性监测网络(CForBio)标准, 我们在该区域建立了一个面积30 ha的森林动态监测样地, 系统调查了样地内胸径 ≥ 1 cm的木本植物, 分析了其物种组成、群落结构、植被类型和生境类型等特征。结果表明, 样地内共记录木本植物179,533株, 隶属49科96属201种, 其中杜鹃花科、山茶科和壳斗科为优势科。样地内有21个物种的重要值 ≥ 1%, 其中猴头杜鹃(Rhododendron simiarum)、木荷(Schima superba)和麂角杜鹃(Rhododendron latoucheae)位列前三。常绿阔叶、落叶阔叶和针叶树种的重要值分别为69.5%、21.8%和8.8%, 植被类型以常绿阔叶林为主, 并随着地形变化与其他植被类型呈镶嵌分布, 反映出该样地较其他低海拔亚热带样地具有明显植被过渡特征。群落平均胸径为6.8 cm, 径级结构呈典型倒“J”型, 群落更新良好。群落垂直分层明显, 乔木层以木荷、黄山松(Pinus taiwanensis)、多脉青冈(Cyclobalanopsis multinervis)和褐叶青冈(C. stewardiana)等物种占优势, 亚乔木层和灌木层则以杜鹃花科植物(猴头杜鹃、麂角杜鹃)为主, 体现出以中山地带典型分布种为主的垂直分层特征。区系组成在科级层面以热带成分为主(51.0%), 在属级层面则以温带成分为主(57.3%)。样地内稀有种比例较高(51.2%)。多元回归树将样地划分为5种生境类型, 总磷、有效钠、坡向和坡度是划分生境类型的关键环境因子。稀有种在高磷、陡坡的过渡生境分布更集中。综上所述, 九龙山30 ha森林动态监测样地较好反映了中亚热带中山原生常绿阔叶林物种丰富、结构复杂、植被组成分异明显且生境异质性强的特征, 为后续长期监测、跨区域比较及相关研究提供了数据基础与研究平台。

Abstract

Aims: Mid-montane evergreen broadleaf forests constitute an important component of subtropical forest ecosystems in China, yet they remain scientifically understudied. Strikingly, the mid-montane zone of Jiulongshan National Nature Reserve contains a large and exceptionally well-preserved primary evergreen broadleaf forest that is highly representative of eastern subtropical China. 

Methods: Following the protocols of the Chinese Forest Biodiversity Monitoring Network (CForBio), we established a 30-ha forest dynamics plot in this region and conducted the first full census of all woody stems with a diameter at breast height (DBH) ≥ 1 cm. Based on these data, we analyzed species composition, community structure, vegetation formations, and habitat differentiation. 

Results: A total of 179,533 woody individuals were recorded in the plot, belonging to 201 species, 96 genera, and 49 families. Ericaceae, Theaceae, and Fagaceae were the dominant families. Twenty-one species had importance values ≥ 1%, with Rhododendron simiarum, Schima superba, and Rhododendron latoucheae as the top three dominant species. The importance values of evergreen broadleaf, deciduous broadleaf, and coniferous species were 69.5%, 21.8%, and 8.8%, respectively. Vegetation formations were dominated by evergreen broadleaf forest and showed a mosaic distribution with other vegetation types along topographic gradients, indicating stronger transitional characteristics than those of lower-elevation subtropical forests. The mean DBH of all woody individuals was 6.8 cm, and the DBH-class distribution showed a typical inverse J-shape, indicating good regeneration potential. Vertical stratification was pronounced, with the canopy layer dominated by S. superba, Pinus taiwanensis, Cyclobalanopsis multinervis, and C. stewardiana, and the sub-canopy and shrub layers dominated by Ericaceae species, especially R. simiarum and R. latoucheae, reflecting a vertical stratification pattern typical of mid-montane forests. Floristic composition exhibited a clear transitional pattern, with tropical elements dominating at the family level (51.0%) and temperate elements dominating at the genus level (57.3%). Rare species accounted for 51.2% of all species. Multivariate regression tree analysis showed that the plot could be classified into five habitat types. Total phosphorus, available sodium, aspect, and slope were identified as the key environmental factors distinguishing habitat types. Rare species were proportionally more concentrated in the transitional habitat characterized by high phosphorus and steep slopes. 

Conclusion: The Jiulongshan 30-ha forest dynamics plot well reflects the characteristics of primary montane evergreen broadleaf forest in the mid-subtropics, including high species richness, complex community composition and pronounced vegetation differentiation. This plot provides baseline data and a research platform for long-term monitoring, cross-regional comparison, and related ecological studies.
