妥打自然保护区人为干扰对白冠长尾雉分布的影响

2007年6月开始对妥打保护区内白冠长尾雉Syrmaticus reevesii的现状进行调查。调查结果与1993年获得的数据进行对比,发现目前白冠长尾雉的分布变狭窄且数量大为减少。核心区内已少有分布,部份转移到缓冲区。相反,白腹锦鸡Chrgsolophus amherstiae和雉鸡Phasianus colchicus已从缓冲区逐渐转移至核心区,且数量呈上升趋势。调查中发现人为干扰是造成白冠长尾雉分布外迁的主要原因。

Influenceof Man-made Interference on Distribution of Reeves's Pheasant in Tuoda Natue Reserve

A survey of habitat status of Reeves＇ pheasant in Tuoda Nature Reserve was conducted from June 2007 to August 2008. Compared with that in 1993,the results showed that the distribution of this pheasant had remarkably changed and its population reduced largely. The groups of Reeves＇s pheasant had almost removed to the buffer area from the core area of Tuoda reserve. On the contrary,Chrgsolophus amherstiae and Phasianus colchicus intruded into the core area from the buffer area. The survey found that this change was caused by interference from local people.
