甘肃盐池湾国家级自然保护区黑颈鹤的种群数量与分布

Number and distribution of the Black-necked Cranes (Grus nigricollis) in Yanchiwan National Nature Reserve, Gansu, China

  • 摘要: 甘肃是黑颈鹤 (Grus nigricollis) 的主要繁殖地之一。2014年4—10月,以甘肃盐池湾国家级自然保护区为研究区域,采用样线法和样点法调查黑颈鹤的数量与分布范围,并了解黑颈鹤的栖息地环境与保护现状。记录到黑颈鹤数量最高为148只,其中亚成体30只,幼体38只。与2012年(140只)、2013年(149只)相比,黑颈鹤数量保持稳定。调查还发现黑颈鹤巢址42个,均分布于海拔3 160~3 260 m的河流湖泊湿地、沼泽湿地等水资源、食物资源较丰富的地方。由于2014年湿地水资源相对减少,导致许多湿地水位下降,水域面积减小,使黑颈鹤的繁殖受到自然条件制约和天敌干扰。建议保护区通过提高管理水平,强化宣传教育,严格执法力度,减少人为干扰来加强黑颈鹤保护和湿地恢复工作。

     

    Abstract: Gansu is one of the main breeding areas of the Black-necked Crane (Grus nigricollis). From April to October 2014, a survey was conducted by the line transect and the point count methods at the Yanchiwan National Nature Reserve. We also investigated the habitat and conservation status of cranes in this area. The peak Black-necked Crane count was 148, including 30 sub-adults and 38 nestlings, which remained stable, compared to the same period in previous years (140 cranes in 2012 and 149 cranes in 2013). We also found 42 crane nests in wetlands, including riverine wetlands, lakes and marshlands, which have abundant water resources and food resources (Carex atrofusca Schkuhr Riedgr), located between 3,160 and 3,260 m a.s.l. Due to the decrease of water level in wetlands, however, some cranes were seriously disturbed by predators. Hence, a detailed management plan is urgently needed to maintain wetlands for the endangered cranes, improve management level, increase public awareness and education, strengthen law enforcement, as well as to minimize disturbance to cranes by human activities.
