成都大熊猫繁育研究基地鸟类多样性

Avian diversity of Chengdu Research Base of Giant Panda Breeding

成都大熊猫繁育研究基地属典型的城市公园绿地,也是城市生态系统和候鸟迁徙通道中重要的鸟类栖息地。查明该区域鸟类物种组成可为城市生态系统及其鸟类多样性保护提供重要的基础资料和科学依据。本研究基于样线调查、环志监测、文献资料和公众科学等多源数据,对1993年以来该区域的鸟类多样性记录进行了全面梳理。结果表明,成都大熊猫繁育研究基地已记录野生鸟类262种,隶属16目56科154属,占成都市鸟类物种数(n=577)的45.4%,在国内城市绿地中名列前茅。记录有国家一级重点保护野生鸟类3种,即青头潜鸭(Aythya baeri)、乌雕(Clanga clanga)和黄胸鹀(Emberiza aureola);国家二级重点保护野生鸟类31种,包括红角鸮(Otus sunia)、凤头鹰(Accipiter trivirgatus)、蓝鹀(Emberiza siemsseni)等。与该基地历史文献资料的鸟类名录相比,本名录新增鸟类95种,新增国家重点保护野生鸟类11种,其中国家一级重点保护野生鸟类青头潜鸭在园区天鹅湖被记录。

Aim:Chengdu Research Base of Giant Panda Breeding serves as a significant urban park green space and an important habitat for avian species within urban ecosystems and migratory bird flyways.This study aims to provide foundational data and a scientific basis for the conservation of urban ecosystems and avian diversity by understanding the composition of bird species in this area.Methods:This study comprehensively reviewed the records of bird species diversity in this area since 1993,using data from transect surveys,bird ringing,literature,and citizen science contributions.Results:A total 262 bird species,representing 16 orders,56 families,and 154 genera,have been recorded at Chengdu Research Base of Giant Panda Breeding.These species account for 45.4%of the total bird species in Chengdu City(n=577),placing the base among the top urban green spaces nationwide in terms of avian diversity.Notably,the base has documented three Class I species of state key protected wild birds:Aythya baeri,Clanga clanga,and Emberiza aureola.Additionally,31 Class II species of state key protected wild birds,including Otus sunia,Accipiter trivirgatus,Emberiza siemsseni,and others have been recorded.Compared to the avian checklist in historical records,the current checklist includes 95 newly recorded bird species,11 species of which are state key protected wild birds.Aythya baeri was recorded in the Swan Lake of Chengdu Research Base of Giant Panda Breeding。Conclusions:Chengdu Research Base of Giant Panda Breeding exhibits significant avian diversity.Employing various survey methods can yield a more comprehensive bird species inventory,which is crucial for understanding the basic characteristics of urban ecosystems.
