Relationship Between Birds Flying Height And Guard Againt The Bird Striking In The Civil Aviation Airport

We carried out a systematic survey on birds flying height of three areas respectively, Hohhot Baita International Airport, Bayannur and Ulanqab civil aviation airport from January to December2012, May2012to April2013and January to December2013.We record the flying height about86kinds of birds by this survey in Hohhot Baita International Airport, Bayannur and Ulanqab civil aviation airport. There are31species of birds in Hohhot airport,66species of birds in Bayannur airport, and75species of birds in Ulanqab airport. Among them,9species are transient migrant,10.47%of the total.27species are resident,31.40%of the total.44species are summer resident,51.16%of the total.6species are winter resident,6.98%of the total.We divide the risk level according to the single factor, the height of birds flying. Severely dangerous species, dangerous species, more dangerous species and general dangerous species respectively accounted for16.28%,17.44%,29.07%and37.21%. Comparing the analytic results of this survey and the investigation of Erenhot civil aviation airport, different and coincident results existed because of the distinct danger level division standard. The same point was elaborated; the differences were discussed and analyzed. The result of the observed survey does not include the birds flying height during migratory time. Since the flying height of migratory birds is beyond the range of human vision. Although the result is estimated, it can reflect the range of birds’height.Based on this research, precautionary measures are probably developed, such as environmental management, reasonable arrangements for flights, driving birds and so on. This study will provide some references to prevent bird strike in future.
