Abstract: Diversity and distribution of breeding birds of 8 regions in the surrounding areas of Lhasa was surveyed in May and June of each year from 2016 to 2019 using the line transect method. A total of 103 species that belonged to 35 families and 15 orders were recorded, which accounted for 20.94% of the total birds species in Tibet, China. Among them, 60 species from 18 families of Passerines were accounted for 58.25% of the total surveyed birds species. In different habitats, shrub grassland had the most bird species with 74 birds species, the habitat near the river was the highest in terms of bird number, diversity index, evenness index and dominance index. In different regions, Dafo Island had the most breeding bird species, Qushui County in Lhasa River were the highest in terms of bird diversity index, evenness index and dominance index. In different breeding periods, the number of species, individual numbers and diversity index in the early period of breeding were slightly higher than those in the late period of breeding. Jaccard index show that the similarity index of breeding birds was higher where the habitat environmental conditions were similar. The breeding bird species gradually increased from 2016 to 2018, and decreased significantly in 2019, and the number of surveyed bird species in 2019 was the lowest within the four years. It is of great significance to carry out the population survey of breeding birds in Lhasa for protecting the diversity of breeding birds in Tibet.
