Qiqihar Airport Bird Distribution And Bird-strike Prevetion Countermeasures

Author conducted the surveys is from2011October to2012October in the Qiqihar airport and the surrounding habitat, and recorded the number and species of birds. Author recorded16orders30families89species, of which61species are summer visitors accounting for68.5%,11resident species accounting for12.3%,2species of winter birds accounting for2.2%,15species migrants accounting for16.9%. Assess the hazard index of the birds recorded with the United States Air Force Base in Denver danger index of Delaware evaluation method, and record the number and the hazard index variation of birds in different seasons in the three kinds of habitat of waters, forest and grass. Screen eight kinds of relative risk birds. They are Rough-legged Buzzard(Buteo lagopus), Long-eared Owl(Asio otus), Heron(Ardea cineria), Common Pochard(Aythya ferina), Common Kestrel(Falco tinnunculus), Northern Lapwing(Vanellus vanellus), Swallow(Barn Swallow, Redrumped Swallow, Sand Martin), Little grebe(Tachybatus ruficollis) and so on(The paper classified the Hirundo as a kind of birds). Author conducted the meet rat statistics and behavior survey of the Rough-legged Buzzard. Studied meet rat statistics and recorded the number variation rule of Long-eared Owl and Common Kestrel. Studied day activities rule and recorded number change variation of the Hiurndo. Studied the day activities rule of the Common Pochard, Heron, Northern Lapwing and Little grebe.Results show that although the danger index of the Common Kestrel, legged Buzzard and Long-eared Owl is not too high, but they can be a threat to the flight safety. The number of the Hirundo are big and activity space is mainly concentrated in the airfield, so they threat the air safety greatly. The Common Pochard and Northern Lapwing often fly cluster in the migratory seasons, and they threat the air safety greatly. The danger index of Heron and Little grebe are high, but they are little impact on the actual flight safety. According to the day activities rule and seasonal activities law, the morning and night are the activities fastigium of the most birds, while the flight behaviors of larger threat to flight safety occur in the two periods. The birds activities are frequent in the spring and autumn. Migratory birds are mostly cluster activities, and the wild goose duck threat the flight safety greatly. The rainfall increases in the summer. When it is a sun day after the rain, the birds act frequently, and the Hirundo act in the airfield mostly. The bird species decreased significantly. The main threat is from Long-eared Owl and Rough-legged Buzzard etc. At last, make the recommendations of system establishment, information analysis, drive and prevention, environmental management and so on for the Qiqihar airport bird strike prevention work according to the survey results.
