大连机场围界外100 m内乔木及招引鸟类的调查

The investigation on the trees and birds attracted in the periphery of the Dalian airport within 100 m

为降低树栖性鸟类对起降航班的威胁性,采用直观法等方法,对大连机场围界外100 m内的乔木及招引的树栖性鸟类进行了调查。结果证明,大连机场近周边有高3 m以上的乔木57种、15 938株,招引树栖性鸟类42种,对大连机场起降航班构成了威胁,使这些乔木成为大连机场间接危险原因;据此提出了要对近周边的乔木进行截冠、降低高度,今后不准在机场近周边栽种乔木的建议。

In order to reduce the threat of arboreal birds on the landing flight,using an intuitive method,conducted a survey of arboreal birds and trees in the periphery of the Dalian airport within 100m.The results proved that the Dalian airport in the periphery have 57 species of trees with a height above 3m,15938 plants totally.42 species of arboreal birds are attracted by the trees,becoming a threat to Dalian airport landing flight.These trees become indirect risk reasons.So we put forward to reduce the height of the trees around Dalian airport and no trees in the vicinity of the airport are allowed to grow in the future.
