城市绿化林带对噪声污染减缓效果的实验研究
Experimental Study on the Mitigation Effect of Urban Green Forest Belt on Noise Pollution

本文旨在探讨绿化林带对噪声污染的减缓效果，通过实验研究不同类型植物对声波的影响。文章首先分析了环境噪声问题及其对人们日常生活的影响，随后重点讨论了利用绿化林带作为控制噪声传播途径的有效方法。研究中，作者选择了具有不同叶面尺寸和密度的观赏植物进行模拟测试，发现大叶面和高密度植物在降噪方面表现更佳。此外，实验还涵盖了多种绿化林带，包括乔木林带、灌木林带和地被植物林带，以评估它们在不同频率下的声学性能。通过对各林带的形态特征和降噪效果进行详细记录和分析，本文构建了一种三层立体绿化林带模型，以实现更高效的噪声控制。研究结果为城市规划提供了科学依据，也为改善城市声环境质量提供了实用的指导。
This paper aims to explore the mitigation effect of green forest belt on noise pollution, and study the influence of different types of plants on sound waves through experiments. This paper first analyzes the environmental noise problem and its impact on people’s daily life, and then focuses on using the green forest belt as an effective way to control the noise transmission way. In the study, the authors selected ornamental plants with different leaf sizes and densities for simulation testing, and found that large foliar and high-density plants performed better in noise reduction. In addition, experiments covered a variety of green forest belts, including arbor, shrub, and ground cover, to assess their acoustic performance at different frequencies. By recording and analyzing the morphological characteristics and noise reduction effect of each forest belt, this paper proposes a three-layer three-dimensional green forest belt model in order to achieve more efficient noise control. The results not only provide a scientific basis for urban planning, but also provide practical guidance for improving the quality of urban acoustic environment.
