为了研究机场内特殊噪音环境(平均噪音值大于80 d B)与人为干扰对鸟类行为的影响,在天津滨海国际机场内选取2个代表性样点:距离跑道最近且飞机起降时噪声分贝最高的样点1;距离跑道最远且有人类居住的样点2.以机场内鸟撞风险高危鸟类麻...为了研究机场内特殊噪音环境(平均噪音值大于80 d B)与人为干扰对鸟类行为的影响,在天津滨海国际机场内选取2个代表性样点:距离跑道最近且飞机起降时噪声分贝最高的样点1;距离跑道最远且有人类居住的样点2.以机场内鸟撞风险高危鸟类麻雀作为研究对象,于2016年3月—2017年2月期间采用激光测距望远镜观测其惊飞行为,将有无飞机起降、实验者着装颜色、移动速率作为主要干扰因子,分析不同干扰下麻雀的惊飞距离(FID).结果表明:在噪音分贝最大的样点1中,麻雀全年的FID均高于同时期有人类居住的样点2中的数值;同一样点中,秋冬季的FID均高于春夏季的数值,但季节对于不同干扰方式下麻雀FID的影响不显著(P>0.05).在3个因子中,有无飞机起降对于麻雀的FID影响最显著,是影响麻雀耐受性的主要因素;其次是实验者的移动速率;实验者的着装颜色对麻雀FID的影响最小.总的来看,麻雀在离跑道较近处有较大的FID,在远离飞机起降、有人类居住的样点中有较小的FID,即麻雀对飞机起降噪音敏感,对人为干扰的耐受性较强.展开更多
