摘要
在福建省金门岛西岸的滨海滩地浯江溪口进行了为期 2年的调查。采用每月 2次的定点调查 ,获得鸟类 30科 10 5种的记录。 2 0 0 0年为 2 7科 89种 5 5 14只 ;2 0 0 1年为 2 8科 84种 90 79只。两年种类和数量起伏月变动曲线都有 2个高峰 ,一是在春季 ,另一是在秋季。虽两年高峰点有前后之差 ,但曲线的模式 ,基本上是一致的。滩地的冬候鸟和旅鸟最为显著 ,优势种包括普通鸬 (Phalacrocoraxcarbo)、环颈 (Charadriusalexandrinus)、白腰杓鹬 (Numeniusarquata)、中杓鹬 (Numeniusphaeopus)、翻石鹬 (Arenariainterpres)、黑腹滨鹬 (Calidrisalpina)等。物种多样性指数均以春季最高 ,秋季次之 ,夏季最为贫瘠。
A 2 years with twice a month spotted census of birds was conducted at Wujiang estuary of Jinmen Islet,Fujian Province.A total of 105 species that belong to 30 families were observed.We recorded 5?514 individuals,representing 89 species and 27 families in 2000,and 9?079 individuals,representing 84 species and 28 families in 2001.The curves of the fluctuation of species and individuals of birds in the 2 years were basically the same,there were two peaks on the curve,one was in spring,and the other was in autumn.The most abundance species were common cormorant (Phalacrocorax carbo),Kentish Plover (Charadrius alexandrinus),Eurasian Curlew (Numenius arquata),Whimbrel(Numenius phaeopus),Ruddy Turnstone (Arenaria interpres),and Dunlin (Calidris alpina),which all transient and wintering shorebirds.The species diversity index was the highest in spring,the second high was in autumn,and the lowest was in summer.
