摘    要:对安澜自然保护区和三峡库区的鸟类资源进行了比较分析,结果发现:从数量上看,安澜自然保护区共有鸟 类89种,三峡库区有鸟类331种;从生境上看,安澜自然保护区农田生境鸟类最多(31.25%),三峡库区农田和水 域生境鸟类最多(分别为32.19%和31.34%);从居留类型上看,安澜自然保护区有候鸟34种(38.20%),留鸟53 种(59.55%),三峡库区有候鸟140种(42.30%),留鸟148种(44.71%);从区系上看,安澜自然保护区以东洋界成 分为主(47.19%),三峡库区以东洋界和古北界成分为主(分别为46.83%和42.90%).两地区鸟类相似性系数为 0.27,鹭科物种相似性系数达到0.64.根据安澜自然保护区的实际情况和现状,对加强安澜鹭类自然保护区的建 设工作提出了相关建议.

Abstract:In this paper, a comparative study on bird resources between Anlan Nature Reserve (ANR) and Three Gorges Reservoir Area (TGRA) was carried out. 89 bird species were found in ANR while 331 species were found in TGRA. As far as the habitats are concerned, species number of birds in farmlands was the largest (31.25%) in ANR. In TGRA, most species of birds inhabited in farmlands and water areas which were 32.19% and 31.34% respectively, 34 species of summer migrants and winter migrants (38.20%) and 53 species of resident birds (59.55%) were found in ANR, meanwhile 140 species of summer migrants and winter migrants (42.30%) and 148 species of resident birds (44.71%) were found in TGRA. In ANR, the chief constituent of its avifauna were oriental birds (47.19%). In TGRA, oriental and palearctic bird species (46.83% and 42.90% respectively) were the main constituents of the avifauna. It was shown by comparing ANR and TGRA that the similarity coefficient (SC) of bird species in these two regions was 0.27, and the SC of Ardeidae species was 0.64. In addition, according to the status quo of ANR, some suggestions concerning the management of ANR focusing on species conservation were proposed.
