自然保护区是生物多样性保护的重要形式,对于迁徙水鸟而言,它的规划尤为重要。本研究于2016–2018年间在中国、蒙古国和俄罗斯捕捉6只斑头雁(Anser indicus)、5只白琵鹭(Platalea leucorodia)和10只东方白鹳(Ciconia boyciana)进行卫星追踪,探讨了黄河流域自然保护区对它们栖息地的保护现状。基于4年累积获取的844,592条高频数据,分析了这21只水鸟在黄河流域活动的时间和利用的土地类型,并使用核密度法拟合了3种鸟类的家域。结果表明:3种鸟类均利用黄河流域湿地作为迁徙途中的停歇地,其中一部分白琵鹭幼鸟利用黄河流域湿地作为度夏地,一部分东方白鹳利用黄河三角洲湿地作为越冬地;3种水鸟在黄河流域内的土地利用情况存在差异,斑头雁对草地(49.0%)、裸地(26.2%)与水体(22.5%)的利用率较高,白琵鹭对农田(42.1%)、草地(19.8%)和湿地(19.6%)的利用率较高,东方白鹳对湿地(49.8%)、农田(34.5%)和水体(4.6%)的利用率较高;斑头雁核心的50%家域被现有保护区完全覆盖,而白琵鹭和东方白鹳核心的50%家域被现有保护区的覆盖度分别为1.6%和0,表明后2种水鸟的栖息地极大可能存在保护空缺;同时对覆盖范围内土地类型自身占比进行分析,发现3种鸟类对于裸地、草地和农田的利用偏向于被动选择,而对于湿地和水体的利用表现为主动选择。基于卫星追踪获得的高频数据可以准确反映3种水鸟在黄河流域的停歇情况、土地利用情况及潜在栖息位点。在黄河流域自然保护区的进一步规划中,应关注白琵鹭和东方白鹳适宜生境的保护状况,并建立覆盖全面的保护区。

白琵鹭(Platalea leucorodia)东亚种群在中国、韩国和日本越冬,其中中国越冬群体的分布和数量研究甚少。文章基于鸟类遥测和调查数据,提出了对中国越冬群体度夏和越冬分布范围的修订建议,在国际鸟盟出版的物种分布图基础上,新增蒙古国中部和中国黄河流域河套平原为度夏地;新增江苏沿海地区为越冬地,而在浙江、福建、广东和广西的分布范围仅保留沿海区域。首次准确估计了东亚种群数量约为20000只,包括中国越冬群体数量约为19500只,韩国约300只,日本约80只。相比2012年的种群数量估计值10000只,东亚种群数量已经翻倍,这主要由于中国群体数量的增加。2016~2020年期间,占东亚总数97.5%的白琵鹭分布在中国长江流域的16个关键越冬位点,且50%以上的个体在鄱阳湖越冬。近年来,随着白琵鹭种群数量增加,其在长江的越冬分布范围更加广泛。
