Abstract: From June 2020 to June 2021, the bird diversity of Qingyi Lake provincial wetland park in Ya'an city was investigated by using sample line method and sample point method. Based on 6 field investigations, a total of 98 species of birds belonging to 40 families and 14 orders were recorded. Among them, there were 8 species of national class II key protected birds, 9 species of Sichuan provincial key protected species. There were three species were endemic to China, three species were on the IUCN Red List of endangered species （1 vulnerable and 2 near threatened species）, and seven species were listed in Appendix Ⅱ of CITES. Residence type analysis indicated that resident birds and summer migrants were the main species （80.61%）. Fauna analysis indicated that, among the breeding birds, 50 species （51.02%） were from Oriental Realm, 21 species （21.43%） were from Palearctic Realm and 27 species （27.55%） were widespread species. The species richness was the highest in summer, the Shannon-Wiener index was the highest in winter, while the species richness and Shannon-Wiener index were the lowest in autumn, and the similarity among different seasons was high （C_j=0.212~0.345）. Broad-leaved forest had the highest species richness and Shannon-Wiener index among different habitats, the species richness of coastal wetland habitat was the lowest, while the Shannon-Wiener index of residential habitat was the lowest. Except for aquatic habitats, the similarity of the other five habitats was high （C_j =0.114~0.268）. On the whole, the wetland park was rich in bird resources, which had important ecological monitoring and protection value. It is recommended to carry out regular bird monitoring, strengthen the monitoring and protection of wetland park waters and strengthen the publicity and education of bird protection and law enforcement.
