摘　　要：2011年4～5月、2012年4～5月,采用样线调查和样方调查相结合的方法对福建漳江口红树林国家级自然保护区内鹭科鸟类巢址与影响其选择的因子进行研究。t-检验结果显示,红树基径、盖度、距地面平均高度、植株密度及秋茄比5个参数在巢区样方(n=23)与对照样方(n=37)之间存在显著差异(P<0.05),桐花比、距道路距离、距村庄距离与距池塘距离4个参数存在极其显著差异(P<0.01)。主成分分析表明,植被结构和干扰条件是影响鹭科鸟类巢址选择的主要因子,植被结构不仅能够影响鹭科鸟类群落结构,还受到鹭科鸟类集群繁殖影响。A study of nest-site selection of Ardeidae birds was conducted by plot survey and line transect survey at Zhangjiang Estuary in Fujian from April to May in 2011 and 2012. The characteristics of bird nests were measured at nest site and control plots, the variable collected were used to conduct a t-test to address the habitat factors which may produce influence on nest-site selection. The study result indicated that habitat factors, including base diameter, average height, density, coverage, proportion of tree Kandelia obovata in the coverage were significantly different between nest presence plots （ n -- 23 ） and control plots （ n = 37 ） （ P 〈 0. 05 ）. Also, significant differences existed highly in proportion of tree Avicennia marina, distance to road, distance to village and distance to culture pond （P 〈 0.01 ）. Principal component analysis shown that both of vegetation structure and disturbance sources were the main habitat factors related to nest-site selection of Ardeidae birds . Vegetation structure could influence community structure of Ardeidae birds, while as reflect the assembling breeding behavinr of the birds might influence the vegetation structure.
