Abstract
The study of the effects of highway on birds found that, due to the negative effect of highway, the birds density of forestland and grassland decreased in different degree to about 60%. The overall density of all the birds fell to about 1/3, and the closer from the road, the lower degree of the birds richness. Highway corridor effect, especially traffic noise, affects birds breeding rate; when the equivalent consecutive sound level A on bird habitat is more than 50dB round the clock, the bird breeding density decreases from 20% to 98%, and the birds who born in the road area spread to the habitat which is far away from the road for breeding. Avian phototaxis caused many birds hitting on the lighted buildings or vehicles at night. The exposed power lines along the highway are also a risk factor for a pair of cranes, eagles and other large birds. Hence, it proposes highway construction environmental technology to reduce the adverse effects of the construction and operation of the highway on the birds, and also provides a reference for highway construction biodiversity conservation.
