摘要
2007-2009年期间的2个越冬期,对鄱阳湖国家级自然保护区白鹤Grus leucogeranus、东方白鹳Ciconia boyciana和小天鹅Cygnus columbianus种群数量和分布进行了监测与研究,结果表明这3个物种的数量一般都在12月达到最高,而10月由于候鸟刚刚迁来以及翌年3月已有部分候鸟迁离,故这2个月份鸟类数量相对较少。保护区的9个湖泊中,沙湖是白鹤、东方白鹳和小天鹅极重要的栖息地,而大湖池是东方白鹳和小天鹅极重要的栖息地。监测发现蚌湖已成为白鹤和东方白鹳重要的栖息地,建议将该湖划为保护区的核心区以加强白鹤等濒危物种的保护。
During the 2 winters of 2007 to 2009, a survey of Grus leucogeranus, Ciconia bovciana and Cygnus columbiamts was conducted in Poyang Lake National Nature Reserve. The results indicated that the three species reached their peaks in number in December, and due to new arrivals of the migratory birds in October and departures in March the numbers of birds in these two months were small. In 9 lakes of the reserve, Shahu Lake was the very important habitat for Grus leucogeranus, Ciconia boyciana and Cygntts columbianus , and Dahuchi lake was the important habitat for Ciconia boyciana and Cygnus columbianus. Field monitoring showed that the lake Banghu had become an important wintering site for Grus leucogeranus and Ciconia bo.vciana, and in order to strengthen the protection of endangered species such as Grus leucogeranus, it was suggested that designating Banghu Lake as the core area of Poyang Lake National Nature Reserve.
