江西武夷山国家级自然保护区鸟类多样性调查

A Survey on Avian Diversity in Wuyishan National Nature Reserve,Jiangxi

自2004年5月至2010年11月对江西武夷山保护区鸟类进行跟踪监测和研究的过程中,共记录到鸟类17目51科148属263种,约占中国鸟类种数的19.8%。G-F指数分析表明,保护区鸟类在科一级水平上其多样性更显丰富。研究结果显示,在保护区海拔1 900 m林线以下的各类生境中,鸟类多样性差异不甚显著,但海拔800～1 900 m范围、自然恢复30年以上的次生林和原生林区,是保护区内繁殖鸟类更为偏好的主要生境;保护区鸟类分布呈现出一定的"岛屿现象";保护区内所保有的黄腹角雉(Tragopan caboti)群体被视为人类对该物种认知历史最为长久且相对最为健康的野生种群。

A long term field monitoring work,from May 2004 to November 2010,on birds in Jiangxi-Wuyishan National Nature Reserve has brought the following positive results—263 bird species（under 148 genera of 51 families of 17 Orders） being recorded with 216 species of photos,about 19.8% of the Chinese birds as far known.G-F index analysis indicating remarkably higher the diversity at family level than in other taxon of the locality;field studies also revealing less difference of species diversity of birds appeared in all kind of habitats below the tree line of about 1 900 m,whilst,between 800-1 900 m,birds more preferring to the original forests and those secondary woods recovering for over 30 years,those areas hence being the core habitats for birds.Wuyishan is also functioning as a refuge supporting a small and isolated population of some of those birds mainly occurring in Himalaya-Indo-China or Himalaya-SW China,and,the local population of the Cabot＇s Tragopan（Tragopan caboti） might be considered the healthiest one in nature,with the longest knowledge and understanding of our species,the human being,on the bird.
