| 中文摘要: |
| 2007年10月至2010年3月3个冬季的调查显示,鄱阳湖国家级自然保护区白琵鹭(Platalea leucorodia)种群数量在12月或1月达到峰值,3个越冬期最大种群数量分别为4 757只、10 385只和7 268只。大湖池、沙湖、常湖池是白琵鹭主要的栖息地,每个越冬期在这3个湖泊栖息的白琵鹭种群数量占保护区总数量的比例超过85%。ArcGIS分析显示了白琵鹭在各湖泊的空间分布特点,白琵鹭昼间集群栖息,且多以500只以下相对较小的群体进行栖息。目前白琵鹭在保护区的栖息仍存在一定威胁,文中同时讨论了三峡工程对该物种以及其他鸟类栖息的影响。建议对白琵鹭及其他候鸟进行长期监测,加强候鸟的保护和管理工作。 |
| 英文摘要: |
| A survey was conducted on number and distribution of wintering Eurasian Spoonbills (Platalea leucorodia) at Poyang Lake Nature Reserve from Oct.2007 to March 2010. The highest numbers of the spoonbills were 4 757, 10 385 and 7 268 in winters 2007, 2008 and 2009, respectively, all recorded in December or January.Of nine lakes in the reserve, Dahuchi, Shahu and Changhuchi were three major sites for the spoonbills, accounting for more than 85% of the total number each winter.The spatial distribution characteristics of winters Eurasian Spoonbills at the reserve was shown by ArcGIS analysis.During daytime, Eurasian Spoonbill moved around in flocks, normally less than 500 individuals in each flock.At present, there are still threats to Eurasian Spoonbills and other waterbirds in Poyang Lake, including intensive fishing activities, as well as potential impact from the Three Gorges Dam.A long-term monitoring program of Eurasian Spoonbills and other migratory birds should be established to strengthen the conservation and management of migratory birds in the reserve and for the whole Poyang Lake basin. |
