2011年冬鄱阳湖水鸟数量与分布调查

摘要

鄱阳湖目前是我国最大的淡水湖,是长江中下游地区乃至东亚地区最大和最重要的候鸟越冬地,每年在鄱阳湖越冬的水鸟总数在50万只以上,同时鄱阳湖还是部分全球珍稀濒危物种十分重要的越冬地。坚持开展鄱阳湖越冬水鸟的种群数量调查,对于掌握长江流域乃至全球水鸟种群动态十分重要。2011年冬在鄱阳湖开展了越冬水鸟调查,共记录到越冬水鸟51种59万余只,其中有14个种达到了全球种群数量1%的标准,同时鸿雁、白鹤、东方白鹳的数量超过全球种群数量的估计值。%The Poyang Lake is currently the largest fresh water lake in China, the largest and most important wintering area for migratory birds in middle and lower reaches of the Yangtze River and even in East Asia. Every year, the total number of wintering waterfowls in the Poyang Lake was more than 500 000, while Poyang Lake is still the very important wintering ground for part of the rare and endangered species around the world. Insisting on investigating the population number of wintering waterfowls in the Poyang Lake is very important to grasp the population dynamic of waterfowl at Yangtze River basin, as well as global areas. Investigation of wintering waterfowls in the Poyang Lake was made in the winter of 2011, a total of 590 000 in 51 species of wintering waterfowls was recorded, from them 14 species reached the standard 1% of the world＇s population number, while the number of Anser cygnoides, Grus leucogeranus, Ciconia boyciana was more than the estimated value of the global population number.
