Avian diversity analysis in winter in different habitats of Liuzhou City, Guangxi.

【Objective】Avian diversity in different habitats of Liuzhou City in winter were investigated and analyzed to find out the habitat factors and provide references for city ecological construction. 【Method】Using line transect, species diversity (H′), evenness(J), and similarity index (S) between different habitat communities were calculated for each sample to investigate the structure of community and its diversity. 【Result】A total of 118 bird species, belonging to 42 families of 13 orders, was recorded. Passeriformes was in the dominant position (26 families and 85 species). Residents, winter migrant and passing migrant were 79 species, 34 species and 5 species. In the whole species, oriental species, palaearctic species and cosmopolitan species were 67, 31 and 20, respectively. Diversity index order in different habitats was urban wood village-farmland shrub of rocky mountainlake billabong commercial forest. The similarity index between village-farmland and commercial forest was the highest. 【Conclusion】Spatial heterogeneity and food resources were important factors influencing bird diversity in winter, and bird diversity could be enhanced by optimizing tree structure, improving habitat, and strengthening protection propaganda.
