| 摘 要： | 四川大头茶(Gordonia acuminata)是我国亚热带西南地区常绿阔叶林优势种之一,材质好,生长快而又未被人注意的一种优良树种。四川大头茶种群在不同林分密度下的纯林中,其胸面积最大增长速度是:中密度>高密度>低密度,达到最大增长速度的径级范围都在18cm左右。种群密度随径级增大而减小。种群空间格局呈集群分布,从幼苗到乔木,其集群程度从大到小。

| Abstract: | Gordonia acuminata is one of the species dominating the subtropical evergreen broad-leaved forests in thesouthwest China. In terms of the maximum growth rate of breast area of Gordonia acuminata population inpure forest with different densities, in middensity it is the highest; in high density it is higher; while in lowdensity it is the lonest. The range of diameter class to reach maximum growth rate is about 18cm. The popu-lation density decreases with the increase of diameter class. The distribution pattern is of the clump, fromsaplings to grown-up trees, the degrees of intenisty is on the regular decrease. |
