【摘要】 淇澳岛是广东地区鸟类重要的栖息地和迁徙休憩点，对于维持区域鸟类多样性具有重要意义。于2021年4月至2022年3月逐月进行连续调查，选择样线法和固定样点法相结合的调查方法，共调查12次。结果如下：（1）记录鸟类5465只，隶属于11目30科78种。其中，留鸟41种、夏候鸟31种、冬候鸟49种、旅鸟40种。国家Ⅰ级重点保护鸟类1种，国家Ⅱ级重点保护鸟类6种。（2）鸟类物种多样性指数秋季最高，夏季最低；均匀度指数秋季最高，春季和夏季最低，均为0.75；丰富度指数冬季最高，夏季最低。（3）群落结构上，夏季和秋季差异性最高，Jaccard相异性指数值为0.51；秋季和冬季差异性最低，值为0.30。淇澳岛鸟类群落的季节性变化主要受到冬候鸟和夏候鸟迁入迁出的影响；其中，绝大多数鸟类为水鸟，并且冬候鸟占据数量优势。更多还原

【Abstract】 Qi’ao Island is an important habitat and migration and recreation point for birds in Guangdong,which is of great significance for maintaining regional bird diversity. From April 2021 to March 2022,a continuous survey was conducted month by month. The survey method of combining the transect method and the fixed sample point method was selected. A total of 12 surveys were carried out. The results are as follows:(1)5465birds belonging to 78 species,30 families,11 orders were recorded. Among them,41 species are resident birds,31 species are summer migrants,49 species are winter migrants,and 40 species are migrant birds. There are 1species of state-level I key protected birds and 6 species of state-level II key protected birds.(2)The Shannon-Wiener Diversity Index for bird species is the highest in autumn and the lowest in summer;The evenness index was the highest in autumn,the lowest in spring and summer, both 0.75;The richness index is the highest in winter and the lowest in summer.(3)In terms of community structure,the difference between summer and autumn was the highest,and the value of Jacob’s dissimilarity index was 0.51;The difference between autumn and winter is the lowest,with a value of 0.30. The seasonal changes of bird communities in Qi’ao Island are mainly affected by the immigration and emigration of winter and summer migratory birds;Among them,the vast majority of birds are water birds,and winter migratory birds occupy a dominant number.更多还原
