摘要:

柔毛油杉(Keteleeria pubescens)为中国特有种, 国家二级重点保护野生植物, 以其为优势种的群落分布区极其狭窄, 呈斑块状零星地分布在贵州和湖南的山地和丘陵。为揭示柔毛油杉林的空间分布、群落组成及特征, 于2021-2023年的植物生长季对柔毛油杉林群落开展了全面的样方调查, 在柔毛油杉的分布区内选择调查样地共计4处, 设置样方11个, 调查基本覆盖了柔毛油杉林的所有分布区域。记录柔毛油杉林所有群落的生境、物种组成及数量特征等信息。主要结果有: (1)柔毛油杉林物种组成较丰富, 共记录维管植物102种; (2)共划分为2个群丛组和2个群丛, 即柔毛油杉+常绿阔叶树群丛组和柔毛油杉-草本群丛组; 柔毛油杉+青冈(Quercus glauca)群丛和柔毛油杉-狗脊(Woodwardia japonica)群丛; (3)柔毛油杉林垂直分层明显, 包括乔木层、灌木层和草本层, 乔木层主要有柔毛油杉及栎属(Quercus)、锥属(Castanopsis)、松属(Pinus)等的物种; (4)柔毛油杉更新较差。该研究将为柔毛油杉林及其物种多样性的有效保护提供扎实的科学资料数据。

Abstract:

Keteleeria pubescens is endemic to China and is classified as a national second-class key protected wild plant species. The distribution areas of the K. pubescens communities were extremely narrow, primarily occurred in patches in mountainous and hilly regions of Guizhou and Hunan. To reveal the spatial distribution, community composition, and characteristics of K. pubescens forests, a comprehensive plot surveys of the communities from 2021 to 2023 during the plant growing season. A total of 4 survey sites were selected within the distribution range of K. pubescens forests, with 11 plots established, largely covered all distribution areas of the forests. Information on habitat, species composition, and quantity characteristics of all the forests were recorded. The main results of the quantitative analysis are: (1) K. pubescens forests had a rich species composition, with a total of 102 vascular plant species recorded; (2) Totally classified into 2 Association Groups and 2 Associations, namely, K. pubescens + Evergreen Broadleaf Tree Association Group and K. pubescens - Herb Association Group; K. pubescens + Quercus glauca Association and K. pubescens - Woodwardia japonica Association; (3) The forests’ vertical stratification is obvious, including tree, shrub and herb layers, in the tree layer there were mainly K. pubescens and species of Quercus, Castanopsis, and Pinus; (4) The regeneration of K. pubescens is poor. This study surely provides solid scientific data for effective conservation and management of K. pubescens forests.
