【摘要】 1997～1999年在中国东部沿海地区对黑嘴鸥进行了专项调查.结果表明,冬季黑嘴鸥分布区的北部边界在江苏连云港市云灌县燕尾镇埒子口(34°31′N,119°43′E.),最南到达广西的铁山港(21°35′37″N,109°34′26″E).1997～1998年冬季的种群数量至少4725只.集中分布在浙江的温岭、乐清、瓯海以及江苏盐城国家级自然保护区内.黑嘴鸥夏季分布区北起辽宁丹东东港市以西的大洋河口(39°49′N,123°51′E),向南至江苏的弶港(32°45′N,120°50′E).1998年繁殖季节开始时黑嘴鸥数量至少有4465只.辽宁沿海数量最多(2478只),集中分布在双台子河口保护区内(2403只),其次是山东省(988只)和江苏省(979只).本文初步讨论了黑嘴鸥的栖息地类型和影响黑嘴鸥种群数量变动的主要因素.更多还原

【Abstract】 From 1997 to 1999, a special survey for the distribution and population of the Saun-ders’ gull was conducted at the eastern coast of China. The north boundary of the distribution in winter was at the Yunguan county of Jiangsu Province (34°3l’N, 119°43’E) and the south boundary was at the Tieshan port of Guangxi Province (21°35’37"N, 109°34’26"E). Totally 4725 birds were observed during the winter of 1997-1998 and most of them were distributed in Wenling, Yueqing, Ouhai of Zhejiang Province and Yancheng National Nature Reserve of Jiangsu Province. In summer, the north boundary of the breeding area was at Donggang City of Liaoning Province (39°49’N, 123°51’E) and the south boundary was at Qonggang port of Jiangsu Province (32°45’N, 120°50’E) . In the breeding season of 1998, at least 4465 birds were observed and 2478 of them were in Liaoning, 988 in Shandong and 979 in Jiangsu. This paper also provides the habitat types and factors affecting the distribution and population of Saunders’ s Gull.更多还原
