| 摘 要： | 群落结构图解不仅能反映物种在群落中的地位,也能在一定程度上反映物种的动态及群落的演替趋势,所以它能较全面地比较天然混交林中各种树种在森林中的作用.用第V级大树结构图解和林木结构图解两种方法分别测定了中亚热带常绿阔叶林乔木层物种在森林组成中的优势度.结果表明:第V级大树结构图解能较客观地反映已进入稳定阶段群落的组成结构特征;林木结构图解能较好地反映处于顺向演替阶段群落的组成结构特征.

| Abstract: | A structural graph of communities not only reflects the position of forest species in community, but also reflects the dynamic of species and the succession tendency of communities. Thus, it can illustrate in a full way the function of each species in a naturally mixed forest. There are two ways to determine the superiority of middle-subtropical evergreen and broad-leaved species in a forest: big-tree structural graph (V) and wood structural graph. The results of determination show that big-tree structural graph (V) will reflect the composition characteristics of stable communities while wood structural graph will reflect the composition characteristics of communities in a smooth succession. |
