基于环志数据探讨兴凯湖水鸟的迁徙规律

黑龙江兴凯湖位于中俄交界，该地区水鸟的迁徙路线及其保护状况受到我国及相邻国家政府和保护组织的高度关注。我们整理了兴凯湖水鸟的环志回收数据，对水鸟的迁徙规律进行了分析。结果表明，从2010年至2019年兴凯湖共环志鹤鹳类和雁鸭类968只，回收记录共29只次，其中白枕鹤（Grus vipio）6只次、东方白鹳（Ciconia boyciana）8只次、斑嘴鸭（Anas poecilorhyncha）3只次、绿头鸭（A. platyrhynchos）3只次、琵嘴鸭（A. clypeata）7只次、凤头潜鸭（Aythya fuligula）1只次和豆雁（Anser fabalis）1只次。水鸟环志回收数据揭示了兴凯湖鹤鹳类和雁鸭类的主要迁徙规律，证实了兴凯湖作为东北亚水鸟迁徙廊道的重要性，为我国与相邻国家开展水鸟的联合保护提供科学依据。

Migration Patterns of Waterbird at Khanka Lake Based on the Analysis of Banding and Recovery Data

The Khanka Lake of Heilongjiang Province is located in northeast China, and shared between China and Russia. Waterbird conservation at Khanka Lake is highly concerned by the governments and conservation organizations of China and neighboring countries. We analyzed the waterbird migration patterns of Khanka Lake by summarizing of the banding and recovery data. During 2010 to 2019, of 968 waterbird individuals totally banded, we got 29 records of recovery of 23 individuals, including six White-naped Cranes, eight Oriental White Storks, three Spot-billed Ducks, three Mallards, seven Shovellers, one Tufted Duck and one Bean Goose (Appendix). By analyzing these data, we discovered some important points of waterbird migration patterns, and confirmed the importance of Khanka Lake as a key corridor on the waterbird migration in northeast Asia (Fig.1), and further provided scientific basis for joint conservation of waterbird between China and neighboring countries.
