【摘要】：在夏冬两季监测柳州市柳长路绿化带的噪声值,分析全乔型、乔灌结合型、全灌型3种标准配置方式的典型绿化带降噪效果季节差异。结果表明:各类型绿化林带对城郊公路的交通噪声都有一定的降噪效果,能达到标准要求,但不同配置方式降噪效果不同;从夏冬两季绿化林带降噪效果分析,整体上夏季的降噪效果强于冬季,全灌木型夏冬季的降噪效果接近,乔灌结合型夏冬季降噪值差值为2.24~3.16 d B,全乔木型差异最明显,夏季降噪量比冬季大3.84 d B;在30 m绿化带范围内,0~10 m处可以得到很稳定的降噪量。
[Abstract]:The noise value of the green belt of Liuchang Road in Liuzhou City was monitored in summer and winter, and the seasonal difference of noise reduction effect of the typical green belt among the three standard allocation modes of all-Arbor type, Joe irrigation type and full irrigation type was analyzed. The results show that each type of greening forest belt has a certain noise reduction effect on the traffic noise of suburban roads, which can meet the requirements of the standard, but the noise reduction effect of different configuration methods is different. From the analysis of the noise reduction effect of greening forest belt in summer and winter, the noise reduction effect in summer is stronger than that in winter, and the noise reduction effect in summer and winter is close to that in summer and winter, and the difference of noise reduction value in summer and winter is 2.24 鈮，
