摘　　要：观赏和减噪是篱垣型垂直绿化需要具备的重要效能。文章通过实地调研,选取藤本月季和大花铁线莲为研究对象,使用高精度声级计(TES-1353S)、采用等距样方法对各样方处的减噪值进行测定和计算,并对植物特征信息进行统计和量化;运用SPSS 26.0分析各样方处的减噪值与植物特征的相关性,发现影响2种篱垣型垂直绿化减噪效果的最显著因素均为植物孔隙率;通过计算和比较2种样本植物的减噪能力,还发现大花铁线莲的减噪能力优于藤本月季。文章最后基于2种植物生长过程中孔隙率的变化特点,提出优化减噪效果的种植策略。Ornamental effect and noise reduction are the important functions of vertical greening of hedgerow.Through the on-the-spot investigation,this paper selects the climbing rose and Clematis patens to measure and calculate the noise reduction value of each square by using the high-precision sound level meter(TES-1353S)and equidistant sampling method,and count and quantify the plant characteristic information.SPSS 26.0 is used to analyze the correlation between noise reduction value and plant characteristics,and it is found that the most significant factor affecting noise reduction effect is plant porosity.By studying and comparing the noise reduction ability of the two plants,it is found that C.patens is better than climbing rose in noise reduction ability.According to the changing characteristics of plant porosity during the growth of the two plants,we come up with the planting strategy to improve the effect of noise reduction.
