Abstract:
In Nanping,12 kinds of four types of plant communities in the representative park were chosen,aiming to determine and analyze the effect of their noise reduction. The results showed that different types of plant communities were different in weakening effect of noise, and the growth characteristics, complexity, measuring distance and other factors of the plant community could affect the noise reduction rate of plants communities. Among them, the best effect of noise reduction was the evergreen coniferous broad-leaved forest. And the noise reduction rate of 5 m was 35.72%, and the noise reduction rate of 10 m reached 39.36%. And the relationship between the coverage rate of plant communities and the relative noise reduction rate of white noise exhibited a very significant correlation.
