　　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 月采用樣帶法對呼和浩特白塔機場4 個樣區的鳥類進行了調查, 共記錄到鳥類59 種,
隸屬于10 目26 科。通過分析春季鳥類群落中各鳥種的相對重要值、分布系數、密度和種間相遇概率等群落
特征參數, 結合鳥類在機場及周邊地區的活動行為等綜合因素確定影響飛機飛行安全的危險鳥類。其結果
表明: 構成飛行安全威脅有兩類: 喜鵲和紅隼等23 種鳥類為最危險的鳥類, 雀鷹和金翅雀等8 種鳥類為較危險
的鳥類。

　　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.

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 ,
