浅谈阿里普兰县秋季的常见鸟类

A Brief Discussion on the Common Birds in Autumn in Pulan County,Ngari Prefecture

青藏高原是中亚迁飞通道的重要组成部分,而喜马拉雅山作为全球重要的生物多样性热点区域,对于其西部地区鸟类多样性的研究仍十分有限。该研究于2023年9月上旬采用样点法对阿里普兰县秋季的常见鸟类进行了野外调查,结合从中国观鸟记录中心下载的文献资料,统计出该区域秋季常见鸟类共有76种,隶属13目28科。其中国家一级重点保护鸟类1种,国家二级重点保护鸟类5种,列入CITES附录Ⅰ的保护鸟类有1种,列入CITES附录Ⅱ的保护鸟类有5种。列入世界自然保护联盟濒危物种红色名录近危的有3种,易危1种,濒危1种;列入中国脊椎动物红色名录近危的有4种,易危2种,濒危1种。县区内鸟类资源保护价值高。区系成分分析表明,秋季常见鸟类中有古北种55种、东洋种7种、广布种11种,西藏特有种3种;居留型分析显示,有留鸟22种、旅鸟54种。通过此次调查既丰富了阿里普兰县常见鸟类群落的基础数据,也为阿里普兰县鸟类资源保护提供了科学依据。

The Qinghai-Tibet Plateau is an important part of the Central Asian flyway,and the Himalayas,as a globally important biodiversity hotspot,still have limited research on bird diversity in its western region.In early September 2023,this study used point count method to conduct a field survey of common birds in autumn in Pulan County,Ngari Prefecture.Based on the literature downloaded from the China Bird Watching Record Center,a total of 76 species of birds are common in autumn in this region,belonging to 13 orders and 28 families.Among them,there is 1 species of key protected birds under the national first-class,5 species of key protected birds under the national secondclass,1 species of protected birds listed in CITES Appendix I,and 5 species of protected birds listed in CITES Appendix II.There are 3 endangered species,1 vulnerable species,and 1 endangered species listed in the IUCN Red List of Threatened Species.There are 4 endangered species,2 vulnerable species,and 1 endangered species listed in the Red List of Vertebrates in China.The conservation value of bird resources in this county is high.The analysis shows that there are 55 palaearctic species,7 oriental species,11 widespread species and 3 endemic species to Xizang in autumn.The analysis of residence type shows that there are 22 species of resident birds and 54 species oftraveling birds.This survey not only enriches the basic data of common bird communities in Pulan County,Ali Prefecture,but also provides a scientific basis for the conservation of bird resources in this area.
