环巢湖十大湿地越冬水鸟多样性调查研究

Survey Study on the Wintering Waterbird Diversity in the Ten Wetlands around Chaohu Lake

环巢湖十大湿地是巢湖周边重要的补偿性栖息地,此地水鸟物种丰富,数量众多。本研究于2023年11月至2024年2月,每月对环巢湖十大湿地水鸟进行调查,共记录到越冬水鸟20065只,隶属于7目11科44种,其中斑嘴鸭(Anas poecilorhyncha)和红嘴鸥(Chroicocephalus ridibundus)是环巢湖湿地越冬水鸟群落中的优势物种;肥东十八联圩湿地的水鸟个体数和多样性指数最高;调查记录到IUCN受胁物种7种,国家一级保护鸟类2种,国家二级保护鸟类4种。针对调查结果提出进一步加强越冬水鸟及其栖息地的保护措施,以期为保护湿地水鸟多样性提供参考。

The ten wetlands around Chaohu Lake are important compensatory habitats with rich waterbirds in species and number,where monthly waterbird surveys were conducted every month from November 2023 to February 2024.A total of 20,065 wintering waterbirds were recorded in these wetlands including 44 species in 11 families of 7 orders,in which Anas poecilorhyncha and Chroicocephalus ridibundus were the dominant species in the wintering waterbird community.The number and diversity index of waterbirds were the highest in ShibaLianwei wetland of Feidong County.The recorded waterbirds in the survey include 7 species in the IUCN Red List,2 ClassⅠnational protected species and 4 ClassⅡnational protected ones.Based on the results,targeted measures were put forward to further strengthen conservation of wintering waterbirds and their habitats,so as to provide reference for conservation of wetland waterbird diversity.
