【摘要】 对29个东方白鹳巢(7个天然巢、12个使用过的人工巢、10个未使用过的人工巢)的生境因子进行测量,包括树种、树高、树径、巢位高、隐蔽度、距干扰源的距离(主要是道路)、树和枝的存活情况、巢处等,并采用Mann-WhitneyU检验进行比较,以找出影响东方白鹳巢址选择主要因子。结果表明:树种、树高、巢处、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。在东方白鹳人工招引工作中注意这些主要影响因子,将有效提高种群恢复的效率。更多还原

【Abstract】 29 nests of Oriental White Stork (7 natural nests, 12 utilized artificial nests, 10 un-utilized artificial nests) were spotted and their habitat impacts were measured, which are wood species, wood height, wood diameter, nest height, canopy covers, and distances from disturbance (roads). Mann-Whitney U test was conducted on them to identify main impacts influencing nest selection of Oriental White Stork. The results revealed that the main impacts influencing nest selection contain wood species, wood height, nest position, canopy covers, and distances from disturbance (roads). In addition, we found great significance between nest height (p<0.05) and nest diameter(p<0.05) of natural nests and artificial nests un-utilized. These impacts should be preferred for artificial attraction and population Restoration更多还原
