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)。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).
