Abstract: Avian activities in areas around the airport are potential risks to flight safety. It is of great significance to understand the characteristics of avian diversity at the airport for birdstrike prevention and control. From October 2018 to August 2019, we investigated avian diversity in the internal and external areas of Taiyuan Wusu International Airport using the method of line sampling and net catching. A total of 75 species, belonging to 31 families of 13 orders, were recorded, with the proportion of breeding and non-breeding birds being 60% and 40%, respectively. Using the software of EstimateS to estimate species richness of birds in the survey area, ACE value was 81 species and ICE value was 98 species, indicating that the survey covers 76.53%-92.59% of the total bird species, with a good survey effect. To clarify the impacts of surveyed birds on bird strike prevention and control, we calculated the hazard index with the importance values (IV) and risk factor of the species. The results showed that there were 10 very dangerous bird species at the airport in the whole year, including Anas zonorhyncha, Hirundo rustica,Anas platyrhynchos, Pica pica, Phasianus colchicus, Columba domestica, and Streptopelia chinensis. The results of clustering analysis of avian diversity in six different habitats showed that habitats with strong human disturbance, including residential areas and road greenbelts, had lower species diversity (H=1.35±0.08). Other four habitats, including airport lawn, pond-tideland, farmland, and artificial forest land, were less disturbed by human activities and had higher species diversity (H=1.66±0.04). Therefore, in the bird strike prevention work of airport, it is necessary to carry out targeted management of the ecological environment around the airport anddevelop targeted prevention and control strategies to cope with the activities of dangerous birds.
