    摘要: 本文通过对景观植物及绿化林带对噪声声压级影响的实验测试,发现大叶面尺寸、高叶面密度植物容易对声波产生反射和吸收,具有较好的降噪效果;植物的树干部对噪声的影响较小,应选择最低分枝高度小的植物来构建降噪绿化林带;植株的种植密度和植株的空间占据密度是降低噪声的关键因素,从而提出三层立体降噪绿化林带的构建模式。 The effect of ornamental and forest belt on the sound pressure level of noise has been discussed and tested. Our experimental results show that the plants with large leaf size and big density of leaf tissues have good noise attenuation performance due to their high reflection and absorption of sound waves. The fact that the trunk plays a less important role in the noise reduction indicates that low much-branched plants are very suitable to be applied in the construction of forest belts for noise reduction. Since the density and space distribution of plant are vital for noise reduction, a three-layer spatial construction model can be used in the afforestation for a more effective noise reduction.
