摘　　要：本文应用空间生态位理论,分析了四川南充太和白鹭自然保护区慈竹林内鹭类繁殖季节的群落结构,对影响鹭类混群繁殖时空分布的因素及各种群间的相互关系进行了探讨。结果表明:南充太和白鹭自然保护区栖息有白鹭Egetta garzetta、夜鹭Nycticoraxny cticorax、牛背鹭Bubu lcusibis和池鹭Araeola bacchus 4种鹭类种群。4种鹭类具有明显的水平和垂直分布现象,白鹭、夜鹭的水平生态位宽度较大,在垂直生态位宽度上白鹭、夜鹭、牛背鹭都较大,池鹭的最小;生态位重叠值以白鹭-夜鹭间的最高,夜鹭-池鹭间的最小;4种鹭间的聚类分析结果普遍较高。An observation was carried out on the community structure of Ardeidae birds in the Omei Mountain Bambusa woods of Taihe Little Egret Nature Reserve, during March to June in 2006. Factors influencing the spatial distribution of the colonial breeding egrets and herons, and the interspecific relationship of the community were inquired. The community was made up of little egret, black-crowned night heron, cattle egret and Chinese pond heron. There were obvious characters in the horizontal and vertical distribution. The horizontal niche breadth index of little egret and black-crowned night heron was larger. The vertical niche breadth indices were lager for little egrets, black-crowned night heron and cattle egret, but the smallest for Chinese pond heron. The niche overlap index was larger between little egret and black-crowned night heron, and smaller between black-crowned night heron and Chinese pond heron. The results of cluster analyses are all larger among them.
