武汉桂子山地区冬季鸟类群落结构及多样性研究

Structure and Diversity of Winter Bird Community in Guizi Mountain area,Hubei Province

2005年11月～2006年3月，对武汉桂子山地区冬季鸟类群落进行了调查，共记录鸟类44种，隶属10目22科。有国家Ⅱ级保护鸟类2种，湖北省重点保护鸟类16种；留鸟32种，冬候鸟11种，旅鸟1种，留鸟构成了冬季鸟类的主体；该地区冬季鸟类密度为4．30只／hm^2，物种多样性指数为2．6477，均匀性指数为0．6997。居民点、乔灌林、绿地和水域生境中，乔灌林鸟类多样性最高，数量最多。

Winter bird community in Guizi Mountain area was investigated from November 2005 to March 2006. There were 44 species belonging to 22 families and 10 orders. There were 2 category Ⅱ Nationally Protected species and 16 species with Hubei Provincial protected status. Among them, 32 species were residents, 11 species were winter birds, 1 species was transient migrant. The resident birds was the dominant species, which reflected the character of winter bird community. The bird community densities were 4.30 ind./hm^2. The diversity index of bird community （H） was 2.6477, and eveness index （E） was 0.6997. The paper analyzes the differences of the bird community among different habitats. The diversity index （H＇） in forest habitat was higher than others and the amount of birds was also higher.
