摘　　要：本文根据2003-2010年固定样方调查的大熊猫采食和人为砍伐后拐棍竹残桩的年死亡率和数量动态数据，分析了拐棍竹无性系植株在不同干扰下的生存能力，结果表明：不同龄级不同年份大熊猫采食的残桩植株的年死亡率远低于被人为砍伐的残桩植株，而且留存残桩的生存时间也长于砍伐残桩，从而导致残桩存活数量以及整个无性系种群呈现出截然不同的后果。According to the mortality and quantity dynamics of the remnant stake population of Fargesia robusta eaten by giant pandas and cut by people from 2003 to 2010,analysis was made of the viability of clonal plants of Fargesia robusta under different disturbances. The result showed that the mortality of the remnant stake population of Fargesia robusta eaten by giant pandas was lower than that of F. robusta cut by people, and the survival strength of the fromer was longer than that of the latter, thus resulting in the different consequences in the remnant stake quantities and clonal population of Fargesia robusta.
