黑龙江洪河国家级自然保护区迁徙鸟类多样性研究

The Study on Biodiversity of Migration birds in Honghe Nation Natural Reserve,Heilongjiang Province,China

2003和2004年春、秋两季鸟类迁徙期时,对洪河国家级自然保护区境内迁飞鸟类进行网捕环志,并对其种类及数量进行了相关分析。2年间共网捕环志迁徙鸟95种6072只,隶属6目20科。其中春季78种3011只,秋季81种3061只。春季以燕雀、灰头和田为迁徙鸟类的优势种,每种各环志728、548、403只;秋季以燕雀和灰头的数量占绝对优势,各环志619和542只。对网捕迁徙鸟类进行多样性分析发现:2003年春季迁徙鸟类Shannon-Weaner指数和Pielou均匀度指数最高,H'=3.96;J=0.70。从两年内迁徙鸟类总体看,G指数为3.37,F指数为22.62,DG-F=0.85。这表明该地迁徙鸟类在种、属、科等分类阶元的多样性均较丰富。

The migration birds were captured and banded in Spring and Autumn in 2003 and 2004 in Honghe Nation Natural Reserve. The diversity of number and speeies construction were analysed. The total 95 species and 6072 birds were banded. Among of them, 78 species and 3011 birds were banded in Spring, and 81 species and 3061 birds in Autumn. The dominant species were Brambling （728 ind.）, Black-faced Bunting （548 ind.） and Rustic Bunting （403 ind.） in Spring, and were Bram- bling （619 ind.）, Black-faced Bunting （542 ind.） in Autumn. From the biodiversity analysis on captured birds, Shannon-Weaner Index （H＇=3.96） and Pielou Equitability Index （J=0.70） were the highest. From the analysis on migration number and species in 2003 and 2004, G-index was 3.37, F-index was 22.62, DG-F= 0.85. The result showed that Family, Genus and species were dominant in the reserve.
