呼和浩特白塔机场春季鸟类的鸟击危险等级评估(英文)

Assessing the Hazard Grade of Birdstrike in Spring at Baita Airport, Hohhot (in English)

摘要: 2005年3—5月采用样带法对呼和浩特白塔机场4个样区的鸟类进行了调查,共记录到鸟类59种，隶属于10目26科。通过分析春季鸟类群落中各鸟种的相对重要值、分布系数、密度和种间相遇概率等群落特征参数，结合鸟类在机场及周边地区的活动行为等综合因素确定影响飞机飞行安全的危险鸟类。其结果表明：构成飞行安全威胁有两类：喜鹊和红隼等23种鸟类为最危险的鸟类，雀鹰和金翅雀等8种鸟类为较危险的鸟类。

Abstract: Between March and May 2005, bird communities in four sample plots at Baita Airport were studied using strips methods in Hohhot, Inner Mongolia. A total of 59 species belonging to 10 orders and 26 families were recorded. Based on the principles of avian community ecology, the community parameters were discussed, including the comparative importance value, distribution coefficient, density and probability of interactive encounter. By analyzing these indices, combined with their flight behaviors at the airport and its neighbourhood, we identified bird species that have the potential to threaten flight security at Baita Airport; The results showed that the 23 bird species including magpie and red falcon are the most hazard to flight security and the eight bird species including sparrow Hawk and Greenfinch are the hazard. Furthermore, we assessed the bird species' different hazard grades to flight security.
