摘　　要：在淇澳岛红树林湿地设置7条样带,分别于2005—2007年每年1月对该区冬季鸟类群落特征进行研究。共记录到鸟类63种,隶属12目23科,雀形目种类最丰富;其中留鸟、冬候鸟、夏候鸟分别占66.7%、31.7%和1.6%,水禽和陆禽分别占28.6%和71.4%。鸟类群落总体α多样性指数(H)为3.171,均匀度(J)为0.765;各个样带的H值为0.602～2.853,J值为0.336～0.919,其中滩涂与红树林生境的鸟类群落多样性与均匀度在7种生境中最低。β多样性指数分析表明,滩涂、红树林鱼塘湿地和村落之间的鸟类群落差异较大。根据等级聚类分析的结果,淇澳岛冬季鸟类群落可划分为滩涂水禽、红树林鱼塘湿地鸟类、农田森林鸟类3个群落。Seven transects were set up on the mangrove wetland of Qi＇ ao Island to study the characteristics of avian communities in January, 2005 -2007. 63 species of birds were recorded, which belonged to 12 orders and 23 families. Passerine was most abundant in species. Among 63 species, the proportions of resident, winter migratory, and summer migratory birds were 66. 7%, 31.7% and 1.6%, and waterfowls and terrestrial birds occupied 28.6% and 71.4% , respectively. The overall α diversity index （H） and evenness （J） of the avian communities were 3. 171 and 0. 765, with a variation of 0. 602-2. 853 and 0. 336-0. 919, respectively. Among the 7 hab- itats tested, mudflat and mangrove had the lowest H and J. The β diversity showed that there was a greater difference in the avian communities among mudflat, mangrove-pond wetland, and villages. Based on hierarchical clustering analysis, the avian communities on Qi＇ ao Island in wintertime were grouped into three types, i. e. , mudflat waterfowls, mangrove-pond wetland birds, and farmland-forest birds.
