长沙黄花国际机场鸟类群落物种多样性分析

为了获得长沙黄花国际机场鸟击防范工作所需的鸟类基础性资料,从2005年9月~2006年8月,通过对机场地区5种生境类型鸟类群落的调查与监测,记录到鸟类112种,属16目32科。其中46种属东洋界种类、45种属古北界种类、21种属广布种;留鸟46种、夏候鸟25种、冬候鸟29种、旅鸟12种。经RB频率指数测算,鸟类群落的优势种为白头鹎(Pycnonotus sinensis)、乌鸫(Turdus merula)和树麻雀(Passer montanus)。按鸟类生境分布系数划分,广布型的鸟类有44种,是该区鸟类群落组成的主体。鸟类群落的Shannon-Weiner物种多样性指数为1.607,均匀性指数为0.784。

Analysis of Avian Community Diversity in Changsha Huanghua International Airport

In order to acquiring the avian basal sources for preventing from birdstrike,a background survey and an avian species observation were conducted in Changsha Huanghua International Airport from September 2005 to August 2006.In total,112 species,representing to 32 families and 16 orders were observed,or net captured in 5 habitats.Among them,46 species occur in the Oriental,region 45 distribute limitedly in the Palaearctic,and 21 species are found in both regions.Forty six species are resident birds,29 species of winter migrant,25 species of summer migrant,and 12 species of passage migrant.The analysis of frequency index (RB) reveals that 3 birds Pycnonotus sinensis,Passer montanus,and Turdus merula are the dominant species.Among these birds,44 species are found in various habitats at the surveyed region,and form the main part of the avian communities in the study area.The avian Shannon-Weiner species diversity index is 1.607,evenness index is 0.784.
