Özet

This study was carried out to determine the noise-reduction effectiveness of the Pinus sylvestris L. and Populus nigra L. trees along the E-80 State highway in Erzurum-Turkey. Noise values were taken at three measurement points; open ( without trees and taken as control), the urban forests of pure P. sylvestris L. and P. nigra L. areas, and at four different distances; 0 ( near the noise source), 25, 50 and 75 m from the noise source. At the distance of 25 m from the source, the noise value was 78.5 dB( A) in the control area, which was reduced 75.5 dB( A) and 69.2 dB( A) in the P. nigra L. and P. sylvestris L. areas, with the reduction rates of 24.7 and 31% compared to the control, respectively. This value was 69.6, 67.1 and 64.3 at the distance of 50 m and 64.9, 62.5 and 59.2 at 75 m for the naked, P. nigra L. and P. sylvestris L. areas, respectively. From the results of the study, it was suggested that for the noise pollution from the traffic flow on the roads, in especially the big cities, noise reduction zones with suitable width and plant species should be formed along the main arteries of the cities.
