Abstract: To investigate the impact of urban green spaces on bird diversity in the central urban area of Huangshan City, a samplepoint
method was adopted to investigate bird species, population sizes, and habitats in four urban green spaces of the central district of Huangshan City, conducted from September 2023 to January 2024. The Shannon-Wiener diversity index, Pielou evenness index,Simpson dominance index, and Sørensen similarity coefficient were employed to calculate the α -diversity and β -diversity of bird communities, while the BAS method was used to further decompose β -diversity. The results indicated: （1） A total of 908 birds belonging to 7 orders, 25 families, 41 species were recorded, including one species of national second-class key protected wild animal.（2） Significant differences were observed in bird species, species dominance levels, and community diversity among the four urban green spaces. （3） The overall β-diversity across urban green spaces was 0.252, with the turnover component （βsim=0.181） exceeding the nested component（ βsne=0.071）, suggesting that feature differences between green spaces significantly influenced bird communities.As a crucial migratory corridor for birds, Huangshan City′s results provide a scientific basis for the planning of urban green spaces in the region.

Key words: urban green space, bird diversity, Huangshan City
