A PHYTOCOENOLOGICAL STUDY ON THE EMERGENT VEGETATION IN FUTOU LAKE Ⅰ. THE STRUCTURE OF COM. ZIZANIA LATIFOLIA

  • 摘要: 本文从物种结构、水平结构和垂直结构三个方面结合其时间特征对湖北省武昌县斧头湖的菰群落进行了分析。结果表明:①菰群落的区系组成和生长型较为丰富,菰是该群落中唯一的建群种;②菰群落内部表现出不同物种的种群分布在水平方向上的分化。菰群落内部小环境多样,存在着许多小群落。菰的抽条为群聚分布,表现出形态学格局;③菰群落垂直结构简单,多数情况下仅存在一个挺水植被层。群落生产结构的变化与水位及其本身的生长特性有关。菰群落的地下成层现象也是一个值得注意的问题。

     

    Abstract: The structural feature of Com. Zizania latifolia was described in detail. The community was characterised by its rich flora and growth forms. As a consociation, the dominant species Zizania latifolia determined the environment in the community mainly. The distribution of different populations in the community showed zonation. Owing to the existence of mieroenvironments, there were a lot of microcoenoses in it. The shoots of Z. latifolia showed pattern, they were contagious. The patterns at different scales could be attributed to the branching characters of its rhizom system. The vertical structure was also analysed, usually only one vegetation stratum (emergent) could be distinguished in most area of the community. Its production structure had some unique characters. A preliminary investigation uncovered its subterraneous stratification.
