摘要

Urbanization is significantly affecting urban bird communities, and green spaces in urban river corridor parks provide important shelters and food sources for urban birds, which are important for maintaining the stability of urban ecosystems. This study used nine parks along the Min River in Fuzhou City as the research objects. The study sites were divided into three gradients, U1, U2, and U3, from high to low degrees of urbanization disturbance to explore the differences of bird communities in parks along the riverbanks in areas with different degrees of urbanization. The results showed that: (1) A total of 4941 birds of 78 species were recorded, belonging to 9 orders, 36 families, and 59 genera, with 73.03% of the bird species of the order Passeriformes and the U1 area having the largest number of omnivorous and upper-stratum guild birds. (2) The Shannon index and Chao1 index of birds in summer in the study site differed significantly from those of other seasons, and the species composition of bird communities varied significantly among different seasons. (3) Among the parks in areas with different degrees of urbanization, the highest bird diversity index was found in the U2 area, and there were seasonal differences in the β-diversity of birds in the three parks with different degrees of urbanization disturbance. (4) Bird abundance was significantly and positively correlated with the Shannon diversity index and the Chao1 index of birds in parks along rivers but not significantly correlated with the Shannon diversity index and the Chao1 index in areas with high urbanization disturbance. Meanwhile, abundance was the key factor influencing the change in bird community structure. Overall, green spaces in urban river corridor parks play an important role in protecting urban biodiversity and species migration, and the protection and enhancement of bird populations are beneficial to improving biodiversity in riverine areas. Therefore, in the process of future urban development, relevant protection measures should be proposed and implemented according to the specific conditions of bird communities in different areas, especially in highly disturbed areas, where emphasis should be placed on the attraction of other bird species and the creation of habitats, and the reasonable mixing of garden plants planted to provide habitats and food resources for riverine organisms.
