The Population Dynamics Of Vegetation,Insects And Birds In Jining Airport

With the rapid development of the aviation industry,the occurrence frequency of bird-strike events has been increasing every year,which has become one of the important factors threatening aviation safety,which has caused great losses to the Civil Aviation department and the military,and the International Aviation Federation has upgraded the bird-Strike disaster to "A" aviation disaster.The research and development of the birds in Jining airport is relatively late,the research is very few,and the bird resources are abundant,many migratory birds are in jining in the migration season and the airport bird strike is very hidden.This paper is study on the species and population dynamics of vegetation,insects and birds in the flight area of Jining Airport from Jun.2016 to Jun.2017.And analyzes the effects of vegetation and insects on the species and quantity of birds in the flight area of Jining airport,and puts forward some measures to control the species and population of the birds,so as to reduce the occurrence of bird strike and ensure the safe take-off of the aircraft.The results are as follows:1.In the investigation of Jining airport,it was found that the main vegetation had 24 families and 42 genera 43 species,and the main arbor plants are Populus L.?Salix babylonica Linn.?Pyrus bretschneideri;The main crops are Zea mays L.?Triticum aestivum L.;The main herbs are Digitaria sanguinalis(L.)Scop.?Chloris virgata(L.)Beauv?Eragrostis pilosa(L.)Beauv..It was found that the main insects had 8 oeders 28 families and 35 species,in which the species of Hemiptera was the majority,and the dominant population was Atractomorpha sinensis Bolvar?Rhopalosiphum maidis(Fitch)?Harmonia axyridis(Pallas).The Araneae are also larger in number.The annual insect community richness index of Jining Airport is:Autumn > Summer > Spring > winter.It was found that the main birds have 9 orders 22 families 31 species,in which the species of bird-shaped birds are mostly,of which resident 13 species,migratory birds 15 species,breeding birds 3 species.There are 5 species of highly threatened birds,were Pica pica?Hirundo rustica?Gallinago megala?Charadrius veredus?Streptopelia orientalis.12 kinds of threat,low threat 14 species,jining Airport annual bird Community richness index is: Autumn > Summer > Winter > spring.2.The relationship between the vegetation,insects and birds in Jining airport is as follows: The Populus on the east side of the airport provide good conditions for the nesting and foraging of magpies and turtle doves,and the ponds and canals on the east side of the airport provide foraging and water conditions for Egretta garzetta,Alcedinidae and Gallinagomegala.During the airport investigation,it was found that there was a litter heap with a large number of Musca domestica and spoilage organisms,which provided conditions for the foraging of birds;Around the airport planting with a large crop,especially Zea mays harvest season,is in the Rhopalosiphum maidis,the occurrence of Harmonia axyridis,magpies,Mountain Turtle,The Upupa epops and so on will fall corn kernels and Rhopalosiphum maidis for food,and the airport billboards and elevating high bar lantern to attract the Pica pica nesting,in order to ensure the safety of aircraft take-off and landing increased difficulties.First of all,the large tracts of poplar in the airport fence close to the airport are proposed to be cut by negotiation,for the pond and drain in the airport,it is recommended to strengthen the drainage capacity of the surrounding ditches in order to reduce the ability of the birds to use.The use of the airport bird nets erected in the airport drains,blocking birds come to drink and bathe.If you have economic conditions,you can also lay the ball on the water.Second,the airport April the main threat population for the Araneae,this period Araneae in the baby spider,the status of the spider,a large number,recommended that the airport in April spraying medicine once;airport June The main threat population is the Atractomorpha sinensis,and at the age of three,a large number of birds to provide a sufficient source of food,it is recommended that the airport to spray again in June;the airport flight area October is in the corn harvest season,the main population is the Harmonia axyridis,provides the foraging condition for the bird foraging,It is recommended that the airport be sprayed in October.Finally,for the airport billboard and the lifting type high pole lamp to check regularly,prevent the Pica pica from making nests;more importantly,accurate,timely prediction and prediction can greatly enhance the prevention and control of bird-strike disaster predictability,planning and security,effective organization of the airport personnel,to carry out prevention and control work,improve the social,economic and ecological benefits of bird strike disaster.
