正蓝旗夏季鸟类种类组成及分布特点
Species Composition and Distribution Characteristics of Summer Birds in Zhenglan Banner
2014-2020年及2023年每年的6月和7月,采用样线法对正蓝旗夏季鸟类物种组成及分布特点进行实地调查,共记录到鸟类128种,隶属19目41科,其中非雀形目鸟类18目24科88种,雀形目鸟类17科40种。种类组成以雀形目、鸻形目和雁形目为主;夏候鸟72种,留鸟34种,旅鸟22种;国家Ⅰ级重点保护鸟类4种,国家Ⅱ级重点保护鸟类20种。鸟类区系组成以古北种为主。4种生境鸟类物种丰富度从多到少的排序为湿地(100种)、灌草丛⁃半灌木(43种)、榆树疏林(30种)、草原(29种)。8年期间鸟类种数呈现平稳趋势。重视湿地生境的保护管理工作,同时加大灌草丛⁃半灌木、榆树疏林和草原生境鸟类的监测力度,对正蓝旗夏季鸟类多样性保护具有重要意义。
The species composition and distribution characteristics of summer bird in different habitats in Zhenglan Banner were investigated based on line transect method in June and July from 2014 to 2020 and 2023. A total of 128 bird species belonging to 41 families from 19 orders were recorded, among which 88 species of non-passerines birds in 24 families from 18 orders and 40 species of passerines birds in 17 families were included. The species composition was dominated by Passerines, Charadriiformes and Anseriformes. There were 72 species of summer migratory birds, 34 residents and 22 passing birds, including 4 species of first-class national protected bird and 20 species of second-class national protected bird. In the avian fauna, Palearctic realm species of birds were dominant. In term of the habitant, birds were the most abundant in Wetland (100 species), followed by Shrub-subshrub (43 species), Elm woodland (30 species) and Steppe (29 species). The number of bird species presented a stable trend from the data of 8-year period. The research suggested that it was of great significance to pay attention to the protection and management of wetland habitats and increase the monitoring of birds in shrub-subshrub, elm woodland and steppe habitats.
