Abstract:The bird strike is a global aviation problem. With the improvement of ecological environment and increase in the number of flights, bird strikes have increased year by year. Scientific and rapid identification of the key areas for high-risk bird control around the airport, and the rational use of landscape ecology to lay out and plan bird strike control methods are blank points in airport bird strike research. In this study, taking an airport in north China as an example, the distribution patterns of three high-risk birds around the airport were obtained through bird situation and ecological environment investigation. By constructing the ecological safety pattern of high-risk birds and combining the ideas of regional prevention and control, we finally got the ecological security pattern of the prevention and control of high-risk birds in the airport. In this way, the patches, corridors and strategic points that need to be driven, guarded and lured were identified, and then a two-way bird repelling strategy combining thrust and gravity was adopted. The results showed that: (1) within 8 km of the the airport, there were more herons and dense corridors. Though anser and gulls had less habitat, there were still corridors crossing the field. The woodland and water area within this scope should be controlled to cut down habitats of heron and flight corridors for high-risk birds. (2) Within 8-15 km of the airport, the protection of ancestral ducks should be focused on, and the corridors for the flight of ancestral ducks to 8 kilometers should be cut off in time, strengthening the protection and transformation of the bird flight corridors that connect 15 kilometers range. (3) The attraction of birds should be increased within 15-20 km of the airport, and a continuous protection strategy point and stepping stones for bird flight should be created to form a circular flight corridor, which keep high-risk birds within a safe range.
