甘肃多儿国家级自然保护区夏季鸟类多样性及垂直分布
The diversity and vertical distribution of summer birds from Gansu Duoer National Nature Reserve
摘要
Abstract
An investigation on the bird community structure and diversity of the Gansu Duoer National Nature Reserve is carried out in the July and August of 2015 . The results show that there are 95 species which belong to 29 families and 8 orders of all the recorded breeding birds . In the four kinds of habitats along different elevation gradients , bird diversity is the highest in broad-leaved forest (47 species , diversity index :3.34) , while it is lowest in Alpine shrub and Bare rock habitats (23 species , diversity index :2.90) , and these show a negative correlation between abundance and diversity index of the bird community and elevation . In the studied brids of the reserves , there are 74 (77.89％ ) Widespread species ,8 (8.42％ ) Palaearctic species and 13 (13.68％ ) Oriental species , and the avian distribution pattern is mainly composed of Himalayan-Hengduan mountains type (33 species , 34.73％ ) , Spreading type(16species ,16.84％ ) and Palaearctic type(12species ,12.63％ ) . The dominant species are widespread (over 70％ ) , a few individuals belong to Oriental species and Palaearctic species in different altitudinal habitats ,which reflect a junctional feature of brids in the reserve among Palaearctic of Tibetan plateau region , Oriental of central China and the southwest China region in the fauna characteristics . Typical species of Tibetan plateau are Chinese grouse (Bonasa sewerzowi ) , Snow Partridge (Lerwa lerwa) , Temminck's Tragopan(Tragopan temminckii),Long-tailed Thrush(Zoothera dixoni),Snow Pigeon (Columba leuconota) , etc .关键词
