摘要
对黑龙江省洪河国家级自然保护区17个东方白鹳巢(其中7个天然巢,10个未使用的人工巢)的生境因子进行了测量,并采用Mann-WhitneyU检验进行了比较,结果表明:树种、树高、巢位高、隐蔽度、距干扰源(道路)距离是影响巢址选择的主要影响因子。此外,天然巢同未使用过的人工巢的巢高(P<0.05)和巢径(P<0.05)存在着显著性的差异。
An experiment was conducted to measure the habitat factors of seventeen （7 is nature, and 10 is man-made） nests of Oriental White Stork in Honghe Nature Reserve. Mann-Whitney U test was used to compare the results. Results showed that the main factors influencing nest-site selection are tree species, tree height, nest position height, canopy covers, and distance from interference sources （roads）. Moreover, significant differences in nest height （ P 〈 0.05 ） and nest diameter （P 〈 0.05 ） were found between natural nests and artificial unutilized nests.
