Water Birds and Their Ecological Distribution in Liaocheng of Shandong Province

报道了聊城境内水鸟种类及其 1 991～ 2 0 0 0年间的分布变动。结果显示 ,聊城境内有水鸟 7目 1 2科 45种 ,绿头鸭、斑嘴鸭为优势种 ;常见种有小、苍鹭、普通秋沙鸭、白腰草鹬及普通翠鸟 ;珍稀鸟类包括东方白鹳、白琵鹭、大天鹅、中华秋沙鸭、黑尾塍鹬及黑嘴鸥等 6种。本地区 80 %的水鸟数量趋于下降 ,应加强保护工作。

From 1991 to 2000, we surveyed the distribution of water birds in Liaocheng of Shandong Province. Totally 45 species of water birds, belonging to 7 Orders 12 families, were investigated and the dominant species were Anas platyrhynchos and A.poecilorhyncha; the common ones were Tachybaptus ruficollis, Ardea cinerea, Mergellus merganser, Tringa ochropus and Alcedo atthis; the rare ones were Ciconia boyciana, Platalea leucorodia, Cygnus cygnus, Mergellus squamatus, Limosa limosa and Larus saundersi. The populations of 80% of the species were getting decreased. We suggest that the conservation of water birds in this area depends ultimately on the protection of the habitats.
