白洋淀冬季鸟类物种多样性

Diversity of bird species in winter in Baiyangdian Lake

鸟类多样性是湿地生态系统重要的监测指标,为掌握白洋淀冬季鸟类的资源情况,2021年12月至2022年2月采用样线法对白洋淀进行了调查.结果发现:1)共记录鸟类81种,隶属于16目34科,其中冬候鸟18种,留鸟35种,旅鸟21种,夏候鸟7种;2)优势种2种,常见种8种,稀有种19种,罕见种52种;3)国家Ⅰ级重点保护鸟类3种,国家Ⅱ级重点保护鸟类13种;4)鸟类种类12月份最多,鸟类数量1月份最大,Shannon-Wiener指数12月份最高,1月份最低,Pielou指数12月份最高,1月份最低.研究结果表明:白洋淀冬季鸟类资源丰富,是多种国家重点保护鸟类的越冬地,应加强对白洋淀的保护与监管力度.

Bird diversity is an important biomonitoring indicator of wetland ecosystems.To capture the winter bird resources of Baiyangdian Lake,a survey of Baiyangdian Lake was conducted from December 2021 to February 2022 using the sample line method,the results showed that:1)81 species of birds were recorded,belonging to 34 families of 16 orders,including 18 species of winter birds,35 species of resident birds,21 species of migratory birds and 7 species of summer birds;2)2 dominant species,8 common species,19 rare species and 52 seldon found species;3)3 species of birds under national-level one key protection and 13 species of birds under national-level two key protection;4)the highest number of bird species in December and the highest number of birds in January,the highest Shannon-Wiener index in December and the lowest in January,the highest Pielou index in December and the lowest in January.The results of the study showed that Baiyangdian Lake is rich in winter bird resources,with a large number of rare and endangered birds,and is a wintering site for many species of birds of national importance,so protection and supervision of Baiyangdian Lake should be strengthened.
