掌握甘肃安南坝野骆驼国家级自然保护区鸟类和兽类本底资源现状,能为制定生物多样性保护对策提供基础数据。2020年1月至2023年3月,在甘肃安南坝野骆驼国家级自然保护区7处水源地使用红外相机开展兽类和鸟类多样性调查。红外相机野外调查累计11 443相机工作日,共收集到18 773张野生动物照片,其中有效独立照片3 303张,准确鉴定出4目9科17种野生兽类,7目12科32种野生鸟类。调查结果显示:1)国家一级、二级重点保护野生动物分别为10,18种;被《中国生物多样性红色名录》评估为近危(NT)等级以上物种有24种。2)兽类和鸟类群落多样性指数(H)分别为2.67和3.03,Pielou 均匀度指数(J)分别为0.65和0.62。3)相对多度指数(I_RA)前5种野生动物依次为鹅喉羚(Gazella yarkandensis)(I_RA=99.54)、野骆驼(Camelus ferus)(I_RA=53.57)、雪豹(Panthera uncia)(I_RA=35.22)、秃鹫(Aegypius monachus)(I_RA=15.64)、岩羊(Pseudois nayaur)(I_RA=13.81)。调查结果反映出甘肃安南坝保护区兽类和鸟类资源现状,可以为后续生物多样性保护和长期监测提供数据支持和指导。

This study aimed to determine the status of wildlife in An’nanba Wild Camel National Nature Reserve and provide substantial data for diversity conservation.From January 2020 to March 2023,we deployed camera trapping to investigate the diversity of wildlife at water sources in An’nanba,Gansu province,China.We obtained 3 303 photographs of single animals(out of 18 773 total detections)among 11 443 camera-trap days at seven water sources,and identified 17 mammal species(representing to 9 families and 4 orders),and 32 bird species(representing to 12 families and 7 orders).1)Among species,ten of them are listed as the first class in the key protected wild animals of national importance and eighteen are listed as the second class.Twenty-four wildlife species were evaluated as Near Threatened or above by the Red List of China’s Biodiversity.2)The Shannon-Wiener diversity index of the mammal and bird community is 2.67 and 3.03,respectively,and the Pielou evenness index of mammal and bird community is 0.65 and 0.62,respectively.3)Based on the relative abundance index(I_RA),Gazella yarkandensis(99.54),Camelus ferus(53.57),Panthera uncia(35.22),Aegypius monachus(15.64),and Pseudois nayaur(13.81)were ranked as the top most abundant mammals and bird’s species.Our results provided a baseline of the wildlife resource in An’nanba Wild Camel National Nature Reserve,which is essential for biodiversity conservation and long-term monitoring in this area.
