摘　　要：20 0 2年 4月～ 2 0 0 3年 6月对四川九寨沟自然保护区的鸟类进行调查 ,并结合历史文献 ,确认保护区有鸟类 2 2 2种 ,以留鸟和夏候鸟为主 ,占保护区鸟类总数的 86 48%。对保护区繁殖鸟类的区系分析表明 :古北界种类占繁殖鸟总数的 3 3 85 % ,东洋界种类占 5 5 2 1 % ,广布种占 1 0 94% ,可见东洋界种类占优势。保护区内有国家Ⅰ、Ⅱ级保护动物 2 7种 ,我国特有种 1 7种 ,占我国特有种的 2 4 6%。列入CITES名录的有 2 0种。对保护区鸟类的垂直区系分析发现 ,随海拔高度的增加 ,东洋界成分所占比例增加 ,主要是喜马拉雅 横断山区型的比例增加 ,在海拔 3 0 0 0m以上 ,喜马拉雅 横断山区型占绝对优势 ,所占比例超过 5 0 % ;其它东洋界成分 ,随海拔高度的增加所占比例减少。We surveyed the avian fauna at the Jiuzhaigou Nature Reserve from April 2002 to June 2003 and we recorded 222 bird species during the survey.Eightysix percent of the avian species are resident and summer types.Avian funna are composed of 34% species of Palaearctic realm species,55% of oriental realm species and 11% of epidemic species.Twentyseven species are national protected wild animal species,17 are endemic species of China,which accounted for 24^6% of endemic species of China and 20 species are CITES listed.Vertical distribution of avifunna shows the percentage of oriental realm species increasing with the elevation,and those oriental are mostly the birds of HimalayanHengduan mountains distribution type.More than 50% of the species which distributes over 3?000 m are HimalayanHengduan mountains distribution pattern.Along increasing elevation,the percentage of other oriental realm species decrease.
