摘　　要：2005年4月-2005年8月,我们在厦门上李水库对褐翅鸦鹃的野外生态进行了研究,通过聚类分析的方法分析繁殖季节的褐翅鸦鹃与所在鸟类群落的其他鸟类的种间关系.结果表明,在繁殖季节褐翅鸦鹃的竞争种或潜在的竞争种是灰胸竹鸡,其次是红嘴蓝鹊、喜鹊.褐翅鸦鹃与其他鸟类的种间竞争随着它们之间相似性的减少而减少.The field work was performed around Shangli reservoir,Xiamen from April to August in 2005. Cluster analysis was used to explore the community structure of Centropus sinensis and the interspecific relationship between this pheasant and other birds. During the Spring and Summer season, community structure of birds around Shangli reservoir were divided in 5 guilds according to their foraging maneuvers, food substrates and body size. Centropus sinensis was defined as gleaning guilds, which distribute in middle and low part of the food substrates. Additionally, Barnbusicola thoracica ,Urocissa erythrorhyncha, and Pica pica were also included in this guild. At d=2.6,the Centropus sinensis and Barnbusicola thoracica were converged into the same guild （G1） ,then Urocissa erythrorhyncha and Pica pica achieve union at d= 2.0 （G2）,G1 and G2 clustered at d： 3.4. Obviously,the competition between Bambusicola thoracica and Centropus sinensis was the most severest in the community structure of birds,the competition between Urocissa erythrorhyncha and Pica pica was in the next place. The competitive or potential competitive birds of Centropus sinensis are Bambusicola thoracica ,Pica pica ,Urocissa erythrorhyncha. The competitive status of Centropus sinensis with the others is varied according to the comparability among them.
