摘要
陕西牛背梁国家级自然保护区是中国目前唯一以羚牛及其栖息地为主要保护对象的森林和野生动物类型自然保护区。调查表明,保护区内分布有羚牛206～224头,呈片段化分布在6个生境斑块内,以210国道为界,保护区内羚牛的分布格局为西多东少。虽然保护区内羚牛种群数量和分布区均呈缓慢增长的趋势,但频繁的人为干扰,尤其是保护区内公路、铁路建设和由此导致的生境分割,仍威胁着保护区内羚牛种群的持续生存。
Niubeiliang National Nature Reserve of Shaanxi Province is currently the only wildlife reserve which is mainly for protecting takin and its habitats in China. The population size of takin at Niubeiliang is 206 to 224, occupying 6 discrete habitat patches. The takin population was fragmented by 210 National Roads, and takin were more abundant west than east of this high- way. Although takin numbers and area of distribution were slowly increasing, frequent human disturbance such as highway and railway construction and the resulting habitat fragmentation in the Nature Reserve were the major factors causing takin to be lo- cally endangered.
