摘要
2013年11月—2014年10月,采用样线法对三峡机场8 km净空区范围内的鸟类开展调查,并进行鸟类危险系数评估。结果表明:共调查记录到鸟类120种,其中留鸟69种,冬候鸟23种,夏候鸟19种,旅鸟9种;春季物种数最多,为80种,秋季物种数最少,为41种;夏季密度最大(7.10只·hm^(-2)),秋季密度最小(2.26只·hm^(-2));危险系数高的鸟类共13种,其中留鸟10种,夏候鸟3种。因此,在春夏季应加强留鸟的监测,在采用传统驱鸟方式的基础上,积极采取生态防治措施,减少鸟类在机场周边的活动,保障飞机安全飞行。
Birds of the clearance area in Sanxia airport were surveyed by line transect method from November 2013 to October 2014. A total of 120 birds including 69 species of resident ,23 species of winter migrant, 19 species of summer migrant and 9 species of passage migrant were recorded;the number of species came to the peak in spring （80 species）, and came to the lowest in autumn （41species） ;species density is 7. 10 ind hm-2 in summer,and 2. 26 ind hm-2 in autumn. Thirteen bird species were distinguish- ed as high strike risk including 76. 92% of residents and 23.08% of summer migrants. Thus ,it is important to take effective meas- ures such as enhance the monitoring of resident and insectivore birds, carry out ecological controls and integrated protections to re- duce the activities of birds and ensure the flight security.
