摘要
对大明山云贵山茉莉种群结构和动态进行研究。建立了胸径与年龄、树高与年龄两个回归方程 ,表明云贵山茉莉的林木胸径、树高与其年龄存在极紧密的相关。在 2 0年恢复期的群落中 ,云贵山茉莉种群表现为初生增长型种群 ,在 50年的群落中为稳定 (成熟 )型种群 ,在 2 0 0年的群落中则表现为下降型 (中衰型 )种群。说明云贵山茉莉林只是次生常绿阔叶林向地带性常绿阔叶林演替过程中的一个过渡类型。
This paper deals with the structure and dynamics of H uodendron biaristatus population in Daming Mountain.Two regression models which include age with diameter and height have been established.It follows that the age of individual tree of H uodendron biaristatus population had inclose relationship with their diameter and height.The population of H uodendron biaristatus is belong to initial growing type in the 2 0 years community, stational type in the5 0 years,and declining type in the2 0 0 years.H uodendron biaristatus community is a type of transition of the forest succession in this region.
