Abstract
The fundamental way to reduce the risk of bird strike is to manage the ecological environment of the airport and its surrounding areas and affect the ecological chain of birds. Based on a comprehensive survey of animal and plant populations in Meizhou airport, an airport ecological chain network is established, and a improved cascading failure model in coupled map lattices is introduced to simulate the robustness and vulnerability of the network. It is found that airport ecological network will be collapsed around five time series one after another under the external attack. It also shows that the network will have a global breakdown under a very small external perturbation value when Solanum indicum L. and Callidium villosulum Fairmaire are deliberately attacked. The simulation results show that if the airport authorities give priority to governance these populations of animals and plants with higher in-degree, it may reduce bird strike risk. The analysis results provide a theoretical basis for airport bird strike prevention.
Highlights
Flight safety is seriously threatened by bird strike, this problem can be fundamentally solved when the ecological environment of the airport and its surrounding areas is effectively managed
Various methods are used to reduce the food source, water source and habitat of birds in the airport and its surrounding areas, Bird population should be greatly reduced that birds ecological chain has been destroyed
The research on bird strike prevention mainly focuses on collision prevention, bird strike risk assessment, bird repellent equipment model selection, and ecological environment management etc. [1,2,3]
Summary
Flight safety is seriously threatened by bird strike, this problem can be fundamentally solved when the ecological environment of the airport and its surrounding areas is effectively managed. Various methods are used to reduce the food source, water source and habitat of birds in the airport and its surrounding areas, Bird population should be greatly reduced that birds ecological chain has been destroyed. Cascading failure model of complex networks is used to simulate the ecological network[4], the influence of node fault spreading on the whole network can be studied by analyzing the dynamic characteristics of the network, when the ecological network is destroyed as quickly as possible, the bird population in the airport and its surrounding areas can be effectively reduced. In terms of cascading failures, many models have been proposed by scholars at home and abroad[5,6,7,8]. Most of these models are based on simulation to compare the behavior characteristics and diffusion process of cascading failures of various networks under given parameters
