鸟类多样性调查可以为机场提供基础生态学资料,对鸟击防范工作具有指导意义.2013年6月至2014年6月期间,通过样带法和固定半径样点观察法,在安徽池州九华山机场及周围地区共记录了鸟类130种,隶属于13个目、39个科,其中留鸟50种、夏候鸟41种、冬候鸟29种、旅鸟10种,分别占总数的38.46%、31.54%、22.31%和7.69%.统计分析发现该机场地区的鸟类群落组成具有明显的季节性变化,春、夏季观察到的鸟种数明显高于秋、冬季;6月、7月、8月及11月份为全年鸟类活动频次最高的时段.通过优势度指数分析显示,对九华山机场的飞行安全威胁最大的鸟种有崖沙燕、鹭类(白鹭、牛背鹭、池鹭)、秃鼻乌鸦以及椋鸟类(灰椋鸟、丝光椋鸟).建议通过加强机场生境的综合整治和有效管理来有效地防范机场地区鸟击事件的发生.
Bird diversity survey can provide the basic ecological information for the airport, which is instructive for bird strike prevention work.From June 2013 to June 2014, through transect method and fixed radius sampling observation method, in Anhui Chizhou nine Huashan Airport and its surrounding areas recorded a total of 130 species of birds, belonging to 13 orders and 39 families, of which 50 species of resident birds, 41 species of summer migratory birds, 29 species of migratory birds and 10 species of travelers, accounting for 38.46% and 31.54 respectively %, 22.31% and 7.69% respectively.Statistical analysis showed that the composition of bird communities in this airport area had obvious seasonal changes, and the number of bird species observed in spring and summer was significantly higher than that in autumn and winter; in June, July and August And November was the highest frequency of bird activities throughout the year.The dominance index showed that the most threatening bird species for flight safety at Jiuhuashan Airport were the cliff sand swallow, the heron (egret, cattle egret, pond heron) , Bald crows, and starlings (gray starlings, merlus starlings). It is suggested that bird strike be effectively prevented in the airport area by strengthening comprehensive management and effective management of airport habitats.
