摘要
为了解天津北大港湿地的鸭科鸟类种类,2004年11月~2008年3月采用定位观察和线路调查相结合的方法,用计数法和网格计数法取得鸟类种类和数量,并对所得数值采用频率指数估计法,结果为鸭科鸟类8属24种。旅乌24种,占总种数的100%;冬候鸟4种,占总种数的16.7%;留鸟1种,占总种数的4.2%。古北种13种,占总种数的54.2%;全北型9种,占总种数的37.5%;古北-东洋种2种,占总种数的8.3%。明确豆雁(Anser fabalis)、赤膀鸭(Arias strepera)、绿翅鸭(Anas crecca)、绿头鸭(Anas platyrhynchos)、斑嘴鸭(Arias poecilorhyncha)和斑头秋沙鸭(Mergellus albellus)6种为优势种。Shannon-Weiner多样性指数(H'):春季〉秋季〉冬季〉夏季。有国家二级保护鸟类4种。
Anatidae birds in Beidagang Wetland was surveyed from November 2004 to March 2008. There were 24 species which belong to 8 genera.There are 24 species (100%) of passing birds,4 species (16.7%) of winter migrants, 1 species (4.2%) of residents.There are 13 Palaearetic species (54.2%), 9 Holarctic species(37.5% ) ,2 Palaearctic-Oriental species(8,3% ). 6 species of the Anatidae birds are dominant species, including Anser fabalis , Anas strepera , Anas crecca , Anas platyrhynchos , Anas poecilorhyncha, and Mergellus albellus. The sequence from higher to lower of species richness and species diversity by Shannon-Weiner index ( H' ) was : Spring 〉 Autumn 〉 Winter 〉 Summer. 4 species of the second class of the national protected birds are recorded.
