2010年5月—2011年4月,采用样带法和样点法对二连浩特民航机场及其周边的鸟类进行调研,共记录91种鸟类,隶属于14目30科。由于每种鸟类危险程度不同,为了使机场鸟击防范工作更有针对性而引入危险值这一概念,以定量度量鸟类对飞机飞行安全的威胁程度,并给出计算公式。根据危险值的大小将所有记录的鸟类分为严重危险鸟种、很危险鸟种、较危险鸟种和一般危险鸟种4类。根据鸟类的习性和生活环境,对严重危险鸟种和很危险鸟种进行单独分析,并与其他地区机场进行比较。结果表明,这些鸟类具有半干旱荒漠化草原地区的独有特点,在此基础上提出了飞行区内外环境治理、回避鸟类活动高峰期航班的安排及人工驱鸟方法。
From May 2010 to April 2011, samples of birds at Erenhot and its surroundings were surveyed by transect method and sample point method. A total of 91 bird species were recorded, belonging to 14 orders and 30 families. Due to the different levels of danger for each species of birds, the concept of dangerous values has been introduced to make birdwatching work more targeted at airports to quantify the threat posed by birds to aircraft flight safety and to give formulas. According to the size of the dangerous value, all recorded birds are classified as serious dangerous birds, very dangerous birds, more dangerous birds and general dangerous birds. According to the habits and living environment of birds, separate analysis of severely endangered species and very dangerous species is carried out and compared with other regional airports. The results show that these birds have the unique characteristics of the semi-arid desert steppe region. On this basis, the paper puts forward the environmental governance inside and outside the flight area, the flight arrangements to avoid the peak of bird activities and the method to prevent birds.
