山顶苔藓矮林是亚热带山地常绿阔叶林区在极端气候与环境条件下发育的一种群落变型,通过研究优势植物的分布格局与规模,可以有效地指导植被保护与管理活动。在湖南阳明山国家级自然保护区的山顶苔藓矮林区设置 3 个样地,应用相邻格子法对优势种云锦杜鹃(Rhododendron fortunei)进行每木调查,在不同取样尺度(面积)上采用方差/均值比率法(v/m)、负二项参数(k)、丛生指数(I)、平均拥挤度(m^*)、聚块性指数(m^*/m)、聚集指数(Ca)和格林指数(GI)等聚集强度指数对云锦杜鹃种a群分布格局进行分析。结果表明:阳明山山顶苔藓矮林优势种云锦杜鹃种群在北、南、东三个方位上的空间分布格局总体上为聚集分布...

The mountaintop mossy dwarf forest is a community of evergreen broad-leaved forests in subtropical mountains facing extreme climatic and environmental conditions. Understanding the distribution pattern and scale of the dominant tree species in this forest can provide insights for effective management measures and an understanding of the mechanisms of community assembly in subtropical forests. In this study, we established 3 plots to explore the distribution patterns of dominant species in a mountaintop mossy dwarf forest in three directions in the Yangming Mountains in Hunan Province, China.
