嘉陵江南充段冬季水鸟的多样性

Diversity of winter waterbirds in Nanchong Section of Jialing River

  • 摘要: 水鸟多样性监测是湿地生态系统科学保护和管理的重要基础。2022年12月至2023年2月采用固定样线法对嘉陵江南充段水鸟的物种多样性进行了调查,共观察到水鸟32种,隶属7目10科,涉禽类有10种,游禽类有21种。其中,国家二级保护鸟类1种,四川省保护鸟类3种。冬候鸟25种,留鸟5种,夏候鸟1种,旅鸟1种。区系组成上古北界24种,广布种6种,东洋界2种。优势种有斑嘴鸭(Anas zonorhyncha)和赤膀鸭(Mareca strepera)两种,占观察水鸟总数的25.69%。通过相关性分析,干扰强度与涉禽类多样性指数呈显著负相关(r=0.614,P<0.05),河漫滩面积与涉禽种类呈极显著正相关(r=0.708,P<0.01),河漫滩面积与涉禽类多样性呈极显著正相关(r=0.757,P<0.05)。

     

    Abstract: The monitoring of waterbird diversity is an important foundation for the scientific protection and management of wetland ecosystems. A fixed line method was used to investigate the species diversity of waterbirds in Nanchong section of Jialing River from December 2022 to February 2023. A total of 32 species of waterbirds were recorded, belonging to 7 orders and 10 families, with 10 species of wading birds and 21 species of swimming birds. Among these species, there was one species of national second-class protected birds and three species of provincial protected birds. There were 25 winter migratory birds, 5 resident birds, one summer migratory bird and one traveler. In terms of fauna, all winter waterbirds were divided into 24 species in the Palearctic Realm, 6 species in the Widespread Realm and 2 species in the Oriental Realm. The dominant species were Eastern Spot-billed Duck (Anas zonorhyncha) and Gadwall (Mareca strepera), which accounted for 25.69% of the total number of observed waterbirds. Through correlation analysis, the interference intensity was significantly negatively correlated with the diversity index of wading birds (r=0.614, P<0.05), the floodplain area was significantly positively correlated with wading bird species (r=0.708, P<0.01), and the floodplain area was also significantly positively correlated with the diversity of wading birds (r=0.757, P<0.05).
