Change of Community Structure of Wintering Water Birds in the Central City of Leshan

[目的]研究近年来乐山市中心城区越冬水鸟群落结构的变迁。[方法]于2008年1月和2014年1月分别对乐山市中心城区越冬水鸟群落结构进行了调查。[结果]伴随城市化的快速发展,乐山市中心城区"三江"水鸟的群落结构发生了明显变化,以红嘴鸥(Larus ridibundus)和崖沙燕(Riparia riparia)等为代表的中小型鸟类逐步取代大中型的鸭科(Anatidae)鸟类成为群落优势种。[结论]该研究可为评估经济活动和生态环境对乐山市中心城区水鸟群落的影响奠定基础。

[Method] The community structure of wintering water birds was conducted in the central city of Leshan in January 2008 and 2014.[Result] The results indicated that, with the rapid development of urbanization, the community structure of“Sanjiang” water birds changed significant-ly, small-medium-sized birds （e.g.Larus ridibundus and Riparia riparia） were becoming the dominant species instead of big-medium-sized ones （e.g.Anatidae） in the local community of wintering water birds.[Conclusion] The study lays a foundation for evaluating effects of eco-nomic activities and eco-environment on water birds community in the central city of Leshan.
