江西老虎脑省级自然保护区鸟类生物多样性研究

2017年11月至2018年4月,利用样线法对江西老虎脑省级自然保护区鸟类生物多样性进行研究。结果表明:(1)共记录到124种鸟类,隶属13目44科,其中6种国家II级重点保护鸟类,3种被中国脊椎动物红色名录评估为近危(NT)物种;(2)鸟类生物多样性指数为3.98,均匀度指数为0.82;(3)在季节性构成上,冬候鸟32种,夏候鸟28种,留鸟59种,以及5种旅鸟。在地理区系构成上,东洋界61种,古北界45种,广布种18种;(4)老虎脑保护区内常见鸟类有树麻雀(Passer montanus)、白头鹎(Pycnonotus sinensis)、丝光椋鸟(Spodiopsar sericeus)等14物种。通过对江西老虎脑鸟类多样性的研究,为鸟类资源的保护与管理提供依据。

Bird Biodiversity in Tiger-Brain Provincial Nature Reserve,Jiangxi Province,China

From November 2017 to April 2018,we investigated the bird diversity of Tiger-Brain Provincial Nature Reserve,Jiangxi,by sampling using the line-transect method.We recorded 124 bird species representing 13 families and 44 genera.Of the 124 bird species,six are listed as Class II state key protected wildlife in China,three species are listed as Near Threatened in the Red List of China s Vertebrates.The Shannon-Wiener diversity index of the bird community was 3.98,and Pielou s evenness index was 0.82.Thirty-two species were winter visitors,28 were summer visitors,59 species were residents,and five were passage migrants.Sixty-one species represent the Oriental realm,45 species represent the Palaearctic realm,and 18 species are widespread.Fourteen species,including Passer montanus,Pycnonotus sinensis,and Sturnus sericeus,were most common.This research provides a baseline for future monitoring of bird diversity in Tiger-Brain Provincial Nature Reserve.
