摘　　要：采用定位观测的方法,通过对京承和京藏高速公路两侧典型绿化带噪声的测定,定量研究了每组绿化带距干道不同距离处噪声强度的变化以及植物种类、植物株行距和植物配置与噪声强度的关系。结果表明:所测绿化带配置有较明显的降噪作用,其效果取决于绿化带宽度、植物种类、植物株行距和植物配置类型等多种因素。为达到较高的降噪水平,建议交通绿化带宽度不宜小于10 m,应采用枝叶浓密、冠幅较大的植物组合成多层立体的乔灌草相结合的垂直结构。Using fix-position method, it quantitatively studied the changes in noise intensity of green belt with different distances to highway and the relationship between plant species, spacing between plants, plant disposition and noise intensity through detecting the noise of typical green belt on the both sides of Beijing-Chengde highway and Beijing-Tibet highway. The results showed that the disposition of the detected green belts had obvious noise reduction effect, and its effect affected by various factors, such as width of green belt, plant species, spacing between plants, plant disposition, etc.. In order to achieve a high level of noise reduction, it suggests that the width of green belt should not be less than 10 m, and it is better to use an arbor-bush-grass multi-layer vertical structure with thick foliage and wide crown plants.
