摘　　要：不同干扰对羊草种群营养繁殖的影响表现为：放牧和割草均可使羊草种群的芽库存量有大幅度减少，而对冬性枝条的组成则均有较大的促进作用。在果后营养期，羊草种群的芽库输出率放牧地段为５２％，割草地段为７２％，漏割地段为２３％。放牧对羊草种群根茎的形成有明显的限制性影响，而割草则没有明显影响。The vegetative propagation on Aneurolepidium chinense populations in different interferenceconditions were analysed in this paper. The results showed that the storages of bud banks on thepopulation could be greatly lessened, but the developments of winterness stems on the popula-tions could be greatly promoted by grazing and cutting utilizations.In the vegetative growth stageafter fruiting,the output ratios on bud banks of the populations were 52%in the grazing plot,72%in the cutting plot,and 23%in the missing cutting plot. The rhizome developments of thepopulations were obviously limited by the grazing utilization, but were not obviously affected bythe cutting utilization.
