| 中文摘要: |
| 2015年初,黄河三门峡库区发生了大天鹅(Cygnus cygnus)等野鸟感染高致病性禽流感病毒的疫情,为此我们总结了2010年、2014年和禽流感发生后黄河三门峡库区的大天鹅越冬种群状况调查的结果,同时根据大天鹅的彩色标记的回收情况,分析了大天鹅越冬地的稳定性和主要的繁殖地,主要的目是了解大天鹅发生禽流感疫情的原因,有助于我国大天鹅禽流感的监测与防控。根据大天鹅彩色标记的回收结果,在三门峡库区越冬的大天鹅中回收到119只个体,证实是由蒙古国北部和中部的19个湖泊迁徙而来的。回收结果同时表明,大天鹅对三门峡库区越冬地是较为的稳定的,这可能与当地较好的栖息环境与丰富的食物资源有关。通过连续5年的监测,三门峡库区大天鹅越冬种群数量越冬呈明显上升趋势,特别是2015年初三门峡市区天鹅湖湿地公园由410只快速增加到2014年6 317只,其主要原因是2014年湿地公园通过引入黄河水使湿地的水质有了明显的改善,再加上大量的投食玉米等饲料,吸引了库区周边的其他地点众多的大天鹅前来越冬,此次发生高致病性禽流感疫情与此有较大关系。基于此,建议当地政府不要盲目地通过大量投食补饲,造成越冬种群密度过高；同时采取合理有效的措施如在附近建立适宜的栖息地,促进大天鹅种群扩散,这对于大天鹅种群的保护具有重要意义。 |

| s: A highly pathogenic avian influenza (HPAI) H5N1 infected by whooper swans (Cygnus cygnus) and other wild ducks outbroke in early 2015 at Sanmenxia Reservoir Region, China. In order to strengthen the avian influenza surveillance and prevention, we summarized the data of wintering whooper swans population surveys in 2010 and 2015, and analyzed the fidelity on wintering sites based on the color making resightings of whooper swans. A total of 119 individuals resighted at Sanmenxia were confirmed from 19 lakes at the northern and central Mongolia. Meanwhile, whooper swans also showed the better fidelity to Sanmenxia wintering sites, which may be related to its habitats suitability and food richness. According to our survey results, the numbers of wintering whooper swans population at Sanmenxia increased significantly in recent years, especially reached 6,317 individuals in early 2015, and many whooper swans at other wintering site were attracted here, as a result of the better water quality through the diverting Yellow River to Sanmenxia Reservoir and abundant corn food raised by local people, so it is assumed that the HPAI outbreak maybe related to higher population density. Finally, it is suggested that the local government should take effective measures such as establishing a new suitable habitat, to promote population dispersal of whooper swans. |
