Method and system for preventing long-distance linear flying birds from colliding with aircraft

The invention provides a method and a system for preventing long-distance linear flying birds from colliding with an aircraft. The method comprises the following steps: acquiring bird activities on a take-off and landing route; acquiring aircraft trajectory information of the aircraft; extracting a long-distance linear flight activity from the bird activities, and comprehensively evaluating the bird strike probability according to the aircraft trajectory information and the data of the long-distance linear flight activity; and when the bird strike probability is higher than a preset risk threshold value, performing bird repelling according to a preset bird repelling strategy. According to the method, only long-distance linear flying birds are repelled, so that the pertinence of risk prevention is improved, and the problem of bird building adaptability caused by excessive use of bird repelling means is avoided. In addition, bird repelling means are accurately implemented in combination with bird activity rules
