摘要
兴凯湖作为亚太地区水鸟重要的迁徙停歇地以及繁殖地,对丹顶鹤(Grus japonensis)的局域保护有着重要意义。2012~2014年通过样点与样线相结合的方法对兴凯湖保护区春、秋两季丹顶鹤的迁徙数量以及夏季的繁殖数量进行了调查。这3年中兴凯湖地区丹顶鹤的迁徙数量较为稳定,春季迁徙数量51~84只,秋季迁徙数量178~213只;繁殖个体数量呈轻微下降趋势,由2012年的105只下降至2014年的83只;栖息本地的丹顶鹤数量有了明显的增多,2013和2014年分别增长15和9只。丹顶鹤数量调查对了解其地理分布和种群数量变动规律具有重要意义,也为制订保护措施提供科学依据。
As an important migration stopover and breeding site for migratory waterbirds flyway in Asia-Pacific, the Xingkai Lake in southeast Heilongjiang(Fig. 1) is the important wetland for the conservation of Red-crowned Crane(Grus japonensis). From 2012 to 2014, using the methods of point and the transect sampling, we investigated the population number of the Red-crowned Crane at the Xingkai Lake National Natural Reserve in the migration season(spring and autumn) and breeding season(summer). The numbers of Red-crowned Crane were stable during migration seasons in these 3 years, with 51﹣84 cranes in springs and 178﹣213 cranes in autumns; however, the breeding numbers dropped from 105 cranes in 2012 to 83 cranes in 2014(Table 1). The autumn number of Red-crowned Crane from local breeding population increased, with 15 cranes and 9 cranes in 2013 and 2014, respectively.
