位于长江口的崇明东滩是东亚—澳大利西亚候鸟迁飞路线上一个重要的候鸟迁徙停歇地.保护区的环志工作始于1986年,自2002年,每年春季和秋季都进行较系统的环志工作.至2010年底,已环志鸻鹬类46种36 800余只,其中超过95％的鸟佩带了代表长江口地区标识的黑白色足旗.其中大滨鹬、黑腹滨鹬和翘嘴鹬是崇明东滩环志数量最多的3种鸟类,环志数量分别为10631、3 056和2746只.为了便于野外个体识别,保护区于2006年起在环志时尝试使用编码足旗,到2010年,共有9种1 758只鸟佩戴了编码足旗.在环志过程中,总计有20种441只来自不同国家地区的环志鸟被回收.回收鸟中超过一半的鸟为大滨鹬,而且70％的回收鸟是在西北澳洲被环志的,表明崇明东滩与西北澳洲对于迁徙涉禽的保护上有非常紧密的联系.崇明东滩环志研究所获得的数据对于了解东亚—澳大利西亚迁徙涉禽的迁徙研究提供了宝贵资料.%The east coast of Chongming Island at the Yangtze River estuary is an important stopover site for migratory birds in the East Asia-Australasia Fiyway. Bird banding in the nature reserve started in 1986, and regular bird banding was conducted in every spring and autumn since 2002. Up to the end of 2010 more than 36,800 shorebirds of 46 species have been banded and more than 95% of these birds have been marked with leg flags (black and white which designating the region of the Yangtze River estuary) at the east coast of Chongming. Great Knot, Dunlin, and Terek Sandpiper were the three most abundant banded birds, with 10631, 3056, and 2746 individuals being banded respectively. Since 2006, engraved leg flags were attached to 1,758 birds of 9 species. A total of 441 individuals of 20 species from different countries or regions were recaptured during the bird banding period. More than half of these birds were Great Knots and more than 70% were originally banded in northwest Australia. This suggests a close migratory connection between the shorebirds in northwest Australia and the east coast of Chongming Island. The study provided important data for understanding shorebird migration along the East Asian-Australasian Fiyway.
