摘要
本文分析了三种林分类型下冷箭竹种群的年龄结构和表现结构，结果表明．卧龙自然保护区森林植被下的冷箭竹种群处于衰退状态，其株数随年龄而变化；高度结构和径级结构因群落生境、干扰程度和大熊猫的取食不同而有明显差异。
The structures of age and performance of Bashania fangiana population under three types of Stand are analyst in thes paper. Results have shown that the Population of B.fangiana is in a declining condition,the number of its plants varies with the age and its performance (i. e.,height and diameter class)has a significant difference under three kinds of stand owing to its different habitat,disturbed level and panda′s eating.
