近海毛竹林立竹形态特征的环境适应性研究

Study on Morphological Adaptability of Phyllostachys pubescens Plantations to Coastal Area Environment

  • 摘要: 为给近海毛竹林的科学经营和毛竹在沿海防护林建设中的应用提供理论依据,对经营措施一致的近海、内陆毛竹林立竹形态特征进行比较研究。结果表明,近海毛竹林立竹全高、枝下高、胸高处壁厚和相对枝下高均显著或极显著地高于内陆,立竹相对冠长、竹冠相对节间长显著地小于内陆毛竹林,而立竹胸径、相对全高、相对胸高处壁厚和竹冠长、枝盘数、竹冠节间长近海与内陆毛竹林无显著差异。近海临风面毛竹林较内陆毛竹林的强抵御海风能力主要体现在有较大的立竹相对枝下高和较小的立竹相对冠长、竹冠相对节间长。

     

    Abstract: A comparative study on the mophological characteristics of the Phyllostachys pubescens plants grown in the coastal and inland plantations managed with similar measures was conducted in order to provide the scientific management of P. pubescens plantation in the coastal area and application of P. pubescens plantation to the construction of coastal shelterbelt system with theoretical basis. The results indicated that the indices of total bamboo height, under branch height, the bamboo wall thickness at D.B.H. and the relative height under the lowest branch of the coastal P. pubescens plantations were all significantly or extremely significantly higher than those of the inland P. pubescens plantation. Whereas the relative crown length and relative internode length of the coastal P. pubescens plantation were significantly smaller than those of the inland P. pubescens plantation. There were no significant differences in the D.B.H, relative total height, relative wall thickness at DBH, crown length, the number of nodes and the internode length betrween the coastal and inland P. pubescens plantations. The study explained that the coastal P. pubescens plantation was stronger in wind resistance than the inland P. pubescens plantation mainly because the former had relatively larger values of height under the lowest branches and smaller values of relative crown length and relative internode length in the crown.
