五大连池德都机场昆虫资源及对鸟类活动的影响

Insect Resources of Dedu Airport in Wudalianchi and its Influence on Bird Activities

为了分析五大连池德都机场昆虫与鸟类间的相互关系,采用网捕法、黄盘法、灯诱法、样线法等对五大连池机场进行昆虫及鸟类资源专项调查,并对昆虫种类及数量随月份变化情况进行分析。数据显示:机场范围内8~9月昆虫的种类和数量均较多,昆虫数量与鸟类出现频率呈正相关。4种优势鸟类活动区域内昆虫相似度比较:红尾伯劳和红隼活动区域内昆虫相似指数最高,红尾伯劳和凤头麦鸡活动区域内昆虫相似指数最低。本研究从食物链角度提出鸟害防治策略,在有效控制机场昆虫数量的同时,间接减少食虫鸟类的种类及数量,对于北方支线机场的鸟情生态调研及鸟击防范措施的制定提供理论依据。

In order to analyze the relationship between insects and birds in Wudalianchi dedu airport,the author used net catching method,huangpan method,light trapping method and sample line method to investigate the resources of insects and birds in Wudalianchi airport,and analyzed the change of insect species and quantity with the month.The data shows that there are many kinds and numbers of insects in the airport from August to September,and the number of insects is positively correlated with the frequency of birds.Comparison of insect similarity in four dominant Bird Areas:the highest similarity index was found in red tailed Shrike and kestrel areas,and the lowest in red tailed Shrike and chicken areas.From the perspective of food chain,this study puts forward the strategy of bird pest control,which can not only effectively control the number of insects in the airport,but also indirectly reduce the species and quantity of insectivorous birds,providing theoretical basis for the investigation of bird situation and ecology in the Northern Branch Airport and the formulation of bird strike prevention measures.It provides a theoretical basis for the ecological survey of birds in the northern regional airport and the establishment of bird strike prevention measures.
