摘　　要：2009-2013年,采用样方法对阜阳市两个营巢地主要营巢鹭鸟池鹭(Ardeola bacchus)的巢址特征进行了调查,选取了11个巢址变量,营巢树种、最短巢间距、巢高、巢树高、巢树枝下高、巢树胸径、巢树冠径、巢周围1 m半径内植被郁闭度、巢上方郁闭度、巢离树干距离、巢离巢区边缘的距离,运用单因素方差分析和主成分分析方法研究池鹭的巢址特征。结果表明,4个主成分描述了池鹭的巢址特征:巢树因子、高度因子、干扰因子、保护因子,各自的贡献率分别为30.527%、19.456%、15.307%、9.657%。From 2009 to 2013, nest site characteristics of Ardeola bacchus were studied by collecting samples from two herunties in Fuyang. Eleven nest-site variables, i. e. , nest tree species, minimum distance between nests, nest height, height of nest tree, under-branch height, diameter of nest tree at breast height, crown diameter of nest tree, coverage within lm around the nest, coverage above the nest, distance of nest from tree center, distance of nest to heronry edge, were measured. Nest site characteristics of Ardeola bacchus were analyzed with the methods of one-way analysis of variance and principal component analysis. The results showed that four components describing sampled nest habitats are nest tree, height, disturbance and protection, and the contribution rate of them is 30. 527%, 19. 456%, 15. 307%, 9. 657% , respectively.
