太白山自然保护区大熊猫种群结构与分布

Population Structure of Giant Panda in Taibai Mountain

太白山自然保护区是我国大熊猫分布的最北界。为了准确了解保护区大熊猫的生态生物学资料,并制订科学的保护管理对策,2005年4月-2006年4月利用间接推算和直接统计法对保护区大熊猫种群数量与结构进行了深入调查与研究。结果表明:保护区大熊猫种群估计数量为16只,比第3次全国大熊猫调查多3只;保护区存在1个野生大熊猫分布的高密度区:太白河-龙洞沟-海棠河区域;厚畛子区域出现一定程度的竹子开花,影响了太白山大熊猫种群分布的完整性。

Taibai Mountain Nature Reserve is located in the most northern sector of giant panda distribu- tion. To accurately and deeply understand the ecological biology of Taibai Mountain Nature Reserve, and to make scientific management of the protection measures,between April 2005 and April 2006 ,many deep in- vestigations and studies were carried out on species and habitats of giant panda in this region. It was esti- mated that 16 giant pandas lived in the reserve,3 more than the figures of the third national survey. One ar- ea was found to be the dense area of wild giant panda distribution,which was located along Taibai River- Longdong Gap-Begonia River region. In Houzhenzi region bamboo flowering occurred in certain degrees, which affected the integrity of the distribution of giant pandas to some extents in the reserve.
