2010年监测记录到西洞庭湖保护区水鸟81种,35 264只,分别隶属于6目16科,基本上是涉禽和水禽,其中涉禽的形目、鹳形目和水禽的雁形目种类占优势,分别占整个鸟类群落组成的38.27%、19.75%和29.63%.从季节型组成上看,候鸟78种,占水鸟总数的96.29%留鸟2种,占2.47%迷鸟1种,占1.23%.记录到珍稀濒危水鸟12种共2023只,新记录到水鸟2种共4只.从种群数量卜来看,2010年比前几年总体上有所上升,其中水禽数量有所下降,涉禽数量有所增加.气候变化、湿地缺水与人为活动是影响迁徙水鸟的主要因素.开展湿地恢复与改造,加强保护管理为度仍足西洞庭湖保护区今后工作的重点.%In 2010,the monitoring records showed that there were 81 species, 35264 individuals of water birds in West Dongting Lake Nature Reserve. They belong to 6 orders and 16 families, and the majority of them were .shorebirds and waterfowls. Charadriiformes and Ciconiiformes were the dominant orders of the shorebird and Anseriformes in waterfowl, respectively accounting lor 38.27%, 19.75% and 29.63% of the bird communiiy. In view of seasonal forms, there were 78 species of migrating birds accounting for 96.29% of the total number of water bird species, 2 species of residenl hirds accounting for 2.47% and one species of scarce bird accounting for 1.23% of the total number of water bird species. We recorded 12 species of endangered water birds with a total of 2023 individuals, of which two species with a total of four individuals were new records. Population sizes of the water birds increased more or less overall compared to those recorded in last few years, but the number of waterfowls decreased somehow while the number of shorebirds revealed an increase. Climate change, insufficient water in wetlands and human activities were the main factors influencing migrating water birds. Restoration and improvement of the wetlands and strengthening of management and conservation will be future priorities for the West Dongting Lake Natural Reserve.
