A Preliminary Study on the Impact of Hydropower Project Construction on Bird Diversity in the Qinghai-Tibet Plateau Region

Two surveys of avian resources were conducted in the study area of the Duobu Hydropower Station on the Nyang River in Tibet. An analysis was performed on bird species, population size, migratory characteristics, and avian community diversity. Based on these findings, the study examined the impact of the Duobu Hydropower Station project on bird populations and proposed corresponding conservation measures. The results showed that a total of 60 bird species from 29 families and 11 orders were recorded in the region, comprising 2193 individuals. During the breeding season, 35 species from 20 families and 8 orders were observed, while in the wintering season, 39 species from 19 families and 7 orders were recorded. Among these, Passeriformes were the most abundant order. In terms of residency status, resident birds dominated, with 41 species (accounting for 68.33
