杭州湾大桥周边鸟类资源现状调查

杭州湾跨海大桥横跨我国杭州湾海域,位于杭州湾的中心地带。大桥建成以后,鸟撞的事件时有发生,这对来往车辆和鸟类的迁徙造成影响。为此,我们于2008年10月至2009年10月对杭州湾大桥周边的鸟类群落结构进行了调查,并结合30年杭州湾鸟类回收的数据对鸟类迁徙进行了分析,希望为相关管理部门制定保护方案提供基础资料。调查地点的选择是围绕杭州湾大桥进行的,分别是北岸湿地海宁东西湖,南岸湿地慈溪庵东湿地和慈溪四灶浦水库。共记录到鸟类163种,71589只。其中列入中国鸟类红皮书有濒危种东方白鹳(Ciconia boyciana)、黑脸琵鹭(Platalea. minor)；易危种白琵鹭(P. leucorodia)、鸳鸯(Aix galericulata)、黑翅鸢(Elanus caeruleus)、黑嘴鸥(Larus saundersi)、小鸦鹃(Centropus bengalensis),稀有种鹗(Pandion haliaetus)、半蹼鹬(Limnodromus semipalmatus)。研究结果表明,杭州湾水鸟在三个地点的数量呈季节性的变化,由多至少依次为春季、秋季、冬季和夏季；多样性的平均值由高至低依次为夏季、春季、冬季和秋季,不同的生境类型优势种的分布是有差异的。在杭州湾共记录到55只回收鸟,大多数在澳大利亚、新西兰、中国台湾越冬的鸻鹬类,将杭州湾作为迁徙停歇地,尤其在春季北迁时。最后,对杭州湾大桥的管理提出保护建议。

The Survey on the Bird Community around the Hangzhou Bay Bridge in China

The Hangzhou Bay Bridge is located in the center of the Hangzhou Bay. Since the bridge has been completed, birds strike events have often occurred, which may impact both traffic and the migration of birds. Bird community surveys were conducted around the Hangzhou-bay Bridge from October 2008 to October 2009, and the covered birds data about the birds migrating during 30 years in the Hangzhou-bay were also analyzed, aim to establish birds baseline information for the local management government. Survey site were selected as the East-West Lake of the north wetland in Haining, the east of Cixi temple of the south wetland and the Sizaopu reservoir in Cixi around Hangzhou Bay Bridge. A total of 163 species 71589 birds were recorded
