卧龙自然保护区羚牛(Budorcas taxicolor)的分布格局

羚牛是我国一级重点保护动物。近年来,受益于大熊猫自然保护区的严格管护,与大熊猫同域分布的羚牛种群数量得以快速增长。2005—2008年,对卧龙自然保护区羚牛的分布及其时空动态调查表明:羚牛在保护区内的绝大部分(93.33%)区域均有活动痕迹;且年际间的总遇见次数和遇见率之间均没有显著差异(P>0.05),可能是该保护区内羚牛的种群数量增加,分布范围有所扩大的原因。羚牛夏季和秋季主要活动于海拔较高人为活动较少的区域,冬季主要活动于该保护区山体中部的范围,拐棍竹林对羚牛的活动影响较小。保护区管理者需要控制当地村民到海拔较高的区域活动,以避免干扰羚牛的正常活动,或者被羚牛伤害。

The Distribution of Budorcas taxicolor in Wolong National Nature Reserve

Benefiting from strict protection for giant pandas in nature reserves, the population size of Budorcas taxicolor increased rapidly in recent years. The population distribution was surveyed together with the spatio-temporal dynamic change in Wolong National Nature Reserve, from 2005 to 2008. In most areas(ocupying 93.33% of the reserve), traces of B. taxicolor were found, and the total encountered times and encountered rates showed no significant difference for each year, which might mean the increased population size and distribution area in this reserve. B. taxicolor mainly scattered in the places with less human disturbance especially in summer and autumn, and moved to the mid-mountain in winter. Managers should prohibit villagers entering higher places, to avoid disturbing B. taxicolor, or be hurt by them.
