机场Claws驱鸟器的效能评价

Evaluation of the Effectiveness of Claws Dispersing Birds Instruments in an Airport

2007年7-8月,通过调查空军某机场场区内鸟类的种类、数量、飞行频次、飞行方向以及个体行为等参数,对该机场引进的Claws驱鸟器的驱鸟效能进行了定量评价.鸟类调查工作分Claws驱鸟器处理前期、处理期间和处理后期等三个阶段进行.调查结果表明Claws驱鸟器在控制鸟类的种类和数量上十分有效,但是在处理期间,鸟类飞向跑道的频次比处理前期和处理后期均显著增加,可能危及飞行安全.因此建议在飞行后勤保障过程中,在使用Claws驱鸟器驱鸟的同时,应结合其他驱鸟方法,对鸟类进行综合防治以保证飞行安全.

From July to August 2007, a study was conducted in an airport to assess the effectiveness of Claws Dispersing Birds Instruments that were introduced from abroad. The effectiveness was measured quantitatively by comparing bird species composition, abundance, behavior, number and direction of the bird movements at dusk. The fieldwork was carried out in three periods： the pre-treatment period, treatment period and posttreatment period. During the treatment period, the Claws instruments were employed. The results showed that the instruments were effective in reducing the number of bird species and bird abundance. However, during the treatment period, the frequency of birds flying towards the runway was significantly more than that during the pre-treatment and post-treatment period, and could endanger flying safety. So it was suggested that other means of dispersing birds should accompany the Claws instruments during the flying training to ensure complete safety.
