摘要
2010年11月和2011年5月对九寨沟县勿角自然保护区的鸟类区系和多样性作了调查.结合相关资料,共记录有鸟类14目47科226种,约占四川省鸟类种数的33.09%.雀形目鸟类30科143种,占四川省鸟类种数的63.27%.区系特征以本地繁殖鸟和东洋界为主,留鸟148种,夏候鸟41种,冬候鸟28种,旅鸟9种;东洋界和古北界相互渗透,南北过渡,东洋界种116种,古北界种78种,广布种类29种.其中,属国家Ⅰ级重点保护鸟类的有4种,属于国家Ⅱ重点保护鸟类的有27种.勿角自然保护区物种科属水平上多样性较高,反映科属多样性的DG-F指数0.8423;与其他保护区相比较,物种丰富度与多样性仅次于四川唐家河自然保护区和甘肃白水江自然保护区.
The investigation on the avian diversity and avifauna was carried out in Wujiao Nature Reserve in 2010 and 2011. By the consulting data,226 avian species were recorded under 47 families and 14 orders, accounting for about 33.09% of birds species in Sichuan province. Among then, there are 30 families, 143 species of passerine birds in the Reserve, accounting for 63.27% of avian species in Siehuan province. The fauna was characterized with majority of breeding birds in the area and oriental realm species. Oriental realm species and Palaearctic mutual penetration, the north-south transition, 148 species were residents in the nature reserve ;41 species were summer migrants ;28 species were winter migrants and 9 species were passage visitors. Avian funna were composed of 116 oriental realm species, 78 palaearctic realm species, and 29 epidemic species. In addition,31 species belonged to national first-grade and second-grade protected species. Avian G-F index was 0.84 that meant a rich avian diversi- ty. Compared with other nature reserves, species richness and diversity were only after the Tangjiahe Nature Reserve and Baishuijiang Nature Reserve.
