广西架桥岭自然保护区的鸟类

Birds in Jiaqiaoling Nature Reserve,Guangxi

2007年对广西架桥岭自然保护区鸟类资源进行了调查,记录到鸟类175种,隶属13目47科。根据居留类型,留鸟105种,夏候鸟28种,冬候鸟27种,旅鸟15种。国家重点保护鸟类21种。区系以在华南区有分布的鸟类最多,但华中区和西南区成分也占有较大的比例。斑头大翠鸟在架桥岭保护区的发现扩展了其在中国的已知分布区,这与全球气候变暖是否存在一定关系有待进一步研究。鸟类G-F指数分析比较发现广西西部地区鸟类多样性较高,自西向东至中部架桥岭一线后递减。架桥岭保护区的鸟类多样性较为丰富,具有很高的自然保护价值。

A total of 175 bird species were recorded in Jiaqiaoling Nature Reserve in Guangxi,which belonged to 47 families and 13 orders.Among these species,105 were residents,28 were summer migrants,27 were winter migrants,and 15 were passage visitors.Twenty-one species were nationally protected in China.Most of the birds were typical of south China fauna,and some of central China and southwest China fauna.The discovery of Blyth＇s kingfisher（Alcedo hercules）in Jiaqiaoling extended its distribution in China,and its relationship to global warming needs further research.Avian G-F index analysis found that bird species diversity in western Guangxi was high and it decreased towards the east.Bird species diversity of Jiaqiaoling was abundant,suggesting a high value of protection.
