九龙山国家级自然保护区鸟类组成特征分析

  目的  生物资源调查是保护区进行管理和保护的基础，对九龙山国家级自然保护区进行鸟类资源调查分析，可提供目前鸟类群落状况，为鸟类的保护和恢复提供科学依据。  方法  通过整合历史文献、进行鸟类专项调查和红外相机调查，分析九龙山国家级自然保护区的鸟类群落。  结果  共记录鸟类165种，隶属15目49科，主要为留鸟(56.36%)。群落优势种为灰眶雀鹛Alcippe morrisonia和红头长尾山雀Aegithalos concinnus。需重点保护的鸟类共有37种，其中，国家Ⅰ级重点保护鸟类2种(白颈长尾雉Syrmaticus ellioti和黄腹角雉Tragopan caboti)；国家Ⅱ级重点保护鸟类26种；列入IUCN物种红色名录的10种，列入中国脊椎动物红色名录的18种。鸟类地理区系组成上兼具古北界和东洋界成分，但以东洋界(89种，53.94%)为主；121种繁殖鸟中，以东洋界种最多(69.42%)；古北界种在旅鸟和冬候鸟中占比最多(分别为84.62%和100.00%)。  结论  九龙山国家级自然保护区鸟类资源丰富，占浙江省鸟类物种数的30.00%以上；区系组成以东洋界为主，且有向古北界过渡特征。表4参13

Analysis of avian composition characteristics in Jiulongshan National Nature Reserve

  Objective  The investigation of biological resources is the basis of the management and protection in nature reserve. The objective of this study is to investigate and analyze bird resources in Jiulongshan National Nature Reserve and provide scientific basis for the protection and restoration of birds.  Method  The bird community in the research area was investigated and analyzed by integrating historical data, special bird survey and infrared camera survey.  Result  A total of 165 species were recorded, belonging to 15 orders and 49 families, among which resident birds had the highest proportion(56.36%). The dominant species were Alcippe morrisonia and Aegithalos concinnus. There were 37 species in need of special protection, among which there were 2 species of national class Ⅰ protection birds (Syrmaticus ellioti and Tragopan caboti), 26 species of national class Ⅱ key protected birds, 10 species listed in IUCN Red List, and 18 species listed in the red list of vertebrates in China. There were both Palaearctic and Oriental elements in the composition of avifauna, but the Oriental realm was dominant (89 species, 53.94%). Among 121 breeding birds (i.e. the sum of resident and summer birds), the most species were Oriental (69.42%). Palaearctic species occupied the highest proportion (84.62% and 100.00% respectively) of migratory and winter birds.  Conclusion  Jiulongshan National Nature Reserve is rich in bird resources, accounting for more than 30.00% of bird species in Zhejiang Province. The faunal composition is dominated by the Oriental fauna, and has the characteristic of transition to the Palaearctic fauna. Ch, 4 tab. 13 ref.]
