【摘要】 笔者于1987年冬季至1988年春季对唐家河自然保护区离群的独栖羚牛进行了考察研究,获得了数量、分布及冬季活动规律等资料,并在行为生态、越冬适应及死亡限制因素等方面作了较深入的研究。这些老、弱、病、残羚牛离群而独栖生活,也是羚牛个体发生的必然规律;它们日趋衰弱,濒于死亡的边缘也是必然趋势。更多还原

【Abstract】 From the winter of 1987 to the early spring of 1988, we had been observing the solitary takins (Budorcas taxicolor) in the Tangjiahe Natural Reserve and achieved the material on their number, distribution and action laws in winter. Further more we still had done deeper researches on their behavioural (cology, overwintering adaptation and the limited factors of their death. All these takins are either old or weak or ill or physically disabled. They leave their clump and live alone. It is an inevitable law in their individual development. That they arc getting weaker day by day and arc on the verge of death is also an inevitable tendency.更多还原
