漳河源自然保护区鸟类资源调查及多样性分析.

Bird resources in Zhangheyuan Nature Reserve was investigated using samples point method and line transect method from July 2018 to September 2019. Based on field investigation data and previously reported data, 181 bird species were recorded in this Nature Reserve, belonging to 15 orders, 46 families, and 118 genera. Among which, 4 species were first class protected birds, 38 species were second class protected birds at the country level, and 25 species were threatened birds in the Red List of China's Vertebrates. There were 77 species having an oriental distribution, 61 species having a palaearctic distribution, and 43 species having a widespread distribution, respectively. Habitat analysis showed that the order of habitat types from highest biodiversity to lowest biodiversity was forest (4.965)> shrub (4.573)> farmland (3.217)>water area (2.237)>residential area (1.651). The similarity between forest and shrub was highest, while the similarity between forest and water area was lowest. The study enriched the basic data of bird resource diversity in Jingshan Mountains, and provided scientific basis for bird resource protection in Zhangheyuan Nature Reserve. [ABSTRACT FROM AUTHOR]
