摘　　要：2008和2009年的3～5月,对扎龙、洪河、兴凯湖3个自然保护区东方白鹳的巢址选择进行了研究,共测量24个巢址。研究表明,人工巢和天然巢在植被类型、巢基牢固度、巢基类型及距树林距离等因子上差异显著,逐步判别分析表明在区分天然巢和人工巢址生境方面有4个因子发挥重要作用,依照贡献值大小依次是:巢基类型、巢间距、距树林距离、巢基牢固度,正确率达91.7%。主成分分析表明,影响巢址选择的主要因子有4种,依次为食物因子、安全因子、取材因子、巢基因子。The site selection of artificial and natural nests of the oriental white stork was surveyed in 3 nature reserves：Zhalong, Honghe and Xingkaihu from March to May,2008 and 2009,with a total of 24 nests.Results showed that differences were significant for 4 factors：vegetation type,stability of the nest base,nest base type,and distance from the forest and analysis with stepwise discriminate model showed that habitats of natural and artificial nests were distinguished mainly by 4 factors in following order：nest base type,distance among nests,distance from the forest and stability of the nest base,with an accuracy of 91.7%.Principal component analysis indicated that nest selection was influenced by four main factors in the following order：food,safety,fagot fetching and nest base.
