Construction and optimization of plant communities for reducing traffic noise on main roads in Nanjing China

摘要

In this paper, 15 kinds of plant communities in greenbelt of 10 major roads in Nanjing were selected as the measuring objects, and we set every 5m to the shoulder as a measuring spot, then measured the noise attenuation on the spots. The result shows the noise attenuation of plant communities have significant differences. And we analyzed the composition of the communities which have a better effectiveness in noise reduction. At last some optimization suggestions were put forward.
