Abstract: The avian community structure of Xianning city was investigated by line transect method in the spring of 2017. The avian community structure was investigated in four habitat types, the total 3 865 avian was recorded which belonged to 9 orders,28 families and 73 species,the Passeriformes were dominant group accounting for 75.34%,they included 39 resident species that were main elements of the community. Light-vented Bulbul and White-browed laughing thrush were the common dominant species. The maximum quantity of species was in mixed broadleaf forest（52 species）, the maximum avian density was in farmland（63.412 ind/hm²）, both the minimum density and least species were in bamboo forest（17 species, 14.417 ind/hm²）. The Shannon-Wiener index was farmland（2.700）>mixed forest（2.471）>broad-leaved evergreen forests（2.349）>bamboo forest（1.739）（F_3,11=11.245,P=0.003）,the bamboo forest was the lowest（F_3,11=24.320,P=0.001）. The Evenness index was approximately equal among habitats（F_3,11=0.246,P=0.862）. The Dominance index was significantly different（F_3,11=4.516,P=0.039）,the maximum index was in the evergreen broad-leaf forest（0.478）（F_1,11=7.593,P=0.021）,the bamboo forest was the least（0.386）（F_1,11=6.133,P=0.033）. The community similarity index was the highest between the mixed forest and evergreen broad-leaved forest（0.611）, and the least between the farmland and bamboo forest（0.295）. The avian community was influenced by the plant spatial configuration and species,presented a certain diversity and similarity in different habitats in Xianning city. Meantime,the dominant species was the associated species because of the effects of human activities.
