摘要：

喜鹊是古北界常见留鸟.为了揭示环境因素对其巢址利用的影响,探究喜鹊的繁殖与环境因子之间的关系,2019年1月至2021年5月对新乡市喜鹊巢废弃情况进行了调查研究,分析了环境因素与巢被废弃之间的关系.结果显示:(1)共计调查喜鹊巢220个,废弃巢63个,废弃率28.64%;(2)喜鹊巢是否废弃与不同巢树所在生境类型、巢树种植类型、干扰距离存在显著性相关(P<0.05);(3)主成分分析发现,干扰距离和生境类型对废弃巢贡献率达27.97%,表明这2个因子对喜鹊废弃巢有较大影响.

Magpies are common resident birds in the Palearctic Realm.In order to figure out the influence of environmental factors on the utilization of magpie nest sites,the relationship between magpie breeding and ecological environment is deeply explored,from January 2019 to May 2021,the abandonment of magpie nests in Xinxiang City was investigated and the relationship between environmental factors and nest abandonment was analyzed.The results showed that:(1)A total of 220 magpie nests and 63 abandoned nests were investigated,with a discard rate of 28.64%;(2)Whether the magpie nest was abandoned was significantly correlated with the habitat type and planting status of different nest trees(P<0.01),and there was a significant correlation with the interference distance(P<0.05);(3)Principal component analysis found that the contribution rate of disturbance distance and habitat type to abandoned nests reached 27.97%,indicating that these two factors had a greater impact on magpie abandoned nests.
