The aircrafts’ engine efficiency deteriorates sharply throughout the take-off and touchdown at excessive plateau airport. This case will increase the take-off or touchdown distance, aggravating the hidden hazard of birdstrikes at excessive plateau airport. This paper first used GIS to categorise and rasterize the chicken knowledge and calculated the month-to-month Birdstrike Danger Index (BRI) inside 6, 13, and 25 km radii of Lhasa Airport, based mostly on the chicken statement knowledge of Tibet and the birdstrike knowledge of Lhasa Airport from 2015 to 2019. The spatiotemporal relationships between the BRI and the environmental elements round Lhasa Airport had been in contrast by the Geographically or Temporally Weighted Regression (GWR or TWR) mannequin and Geographically and Temporally Weighted Regression (GTWR) mannequin. The outcomes confirmed that the temporal nonstationary impact of environmental elements was extra important than that of spatial nonstationary at Lhasa Airport. In addition to, the composition of land sorts had constructive impacts on birdstrike danger throughout the 6 km radius, and this scope was broader than that of the plain airport. Throughout the 13 km and 25 km ranges, the water distribution and the altitude throughout dry season additionally positively impacted birdstrike danger. Furthermore, the important thing issue to birdstrike danger was the water distribution in December.
