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. Fur2
thermore , we assessed the bird species’different hazard grades to flight security.

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。

Birdstrike has been a problem since nine years af2
ter planes were first manufactured in the early 20th
century , causing severe damage to passengers and pos2
sessions. Nowadays , as a potential danger to flight se2
curity , these incidents call for greater global attention
to the effects of birdstrike . Over the last hundred
years , scientists have changed their focus from increas2
ing plane function to withstand birdstrike to ecological
investigations on birds , prompting renewed global effort
to reduce birdstrike . Recently , much progress has
been achieved in all airports and related institutions
around the world (Fang et al , 2002 ; Li et al , 2001 ;
Wang et al , 1999 ; Yang et al , 1998) . In order to
control the hazard of potential birdstrike at Baita Air2

port , Hohhot , we started an ecological investigation of
birds in a cone area between 2004 and 2005. The
study aimed to assess the species , number , ecological
distribution and daily activities of birds to generate an
integrated method of avoiding birdstrike . Furthermore ,
identifying the bird species in different seasons will
help staff to avoid and control birdstrike on a daily ba2
sis. This paper identifies bird species and their activi2
ties and habitats in spring in order to classify the haz2
ard grade in this season to flight security.

Baita Airport is located in the marginal zone be2
tween urban and rural areas within the Saihan district ,
seven kilometers east of Hohhot municipal Government .

the north and lower in the south. The center of the run2
way is 516 km from Wanbu Huayanjing Tower (Baita
Tower ) . This area belongs to the middle temperate con2
tinental climate zone , the average daily temperature is
618 ℃ and the daily temperature variation is approxi2
mately 10 ℃. The annual average rainfall is 36119 mm ,
evaporation is 1 839 mm , wind speed is 118 m/ s , and
the maximum depth of frozen earth is 116 m.
