- 摘要:
- 以4种北京地区常见绿篱为试材,采用CEL-63X型声级计进行测声的方法,研究了宽度对其减噪效果的影响,以期为绿篱植物在园林降噪的应用提供参考依据。结果表明:1)绿篱具有重要减噪功能,宽度是影响绿篱减噪效果的关键因素。2)根据总减噪量、空白衰减量2个评价量,二者随宽度的变化趋势一致,均呈现出增加的趋势。回归分析表明总减噪量、空白衰减量均与宽度呈对数关系,R2在0.950 0以上。3)根据净减噪量、减噪率2个评价量,二者随宽度的变化趋势一致,在不同宽度区间内的变化情况又有所不同。在0~2.0 m区间,二者随宽度的增加而增加,在此区间下,大叶黄杨、棣棠的减噪效果优于小叶黄杨、金叶女贞。在2.0~4.0 m区间,二者随宽度的增加逐渐下降;在4.0~8.0 m区间,下降趋势逐渐趋于平缓。4)根据减噪能力评价量,随着宽度的增加,绿篱减噪能力逐渐下降,并趋于平缓。回归分析表明减噪能力与宽度呈对数关系,R2在0.900 0以上,在0~2.0 m区间,减噪能力随宽度的变化较快,减噪效果明显,宽度>4.0 m时,减噪能力趋近于0,减噪效果较差。绿篱宽度应设置在2.0 m之内,最大不应超过4.0 m。
- Abstract:
- Taking four kinds of common hedges in Beijing as test materials,the effect of width on noise reduction was studied by using CEL-63x sound level meter,in order to provide reference for the application of hedgerow plants in garden noise reduction.The results showed that,1) hedgerows hadimportant noise reduction function,and width wasthe key factor affecting the noise reduction effect of hedgerows.2) According to the two evaluation quantities of total noise reduction and blank attenuation,the change trend of both with the width wasthe same,showed an increasing trend.Regression analysis showed that the total noise reduction and blank attenuation were logarithmically related to the width,and R2 wasmore than 0.950 0.3) According to the two evaluation quantities of net noise reduction and noise reduction rate,the change trend of them with width wasthe same,and the change in different width ranges was different.In the range of 0-2.0 m,both increased with the increase of width.In this range,the noise reduction effect of Euonymus japonicus and Kerria japonica was better than that of Buxus microphylla and Ligustrum lucidum.In the range of 2.0-4.0 m,they gradually decreased with the increase of width,and the downward trend gradually tended to be flat in the range of 4.0-8.0 m.4) According to the evaluation quantity of noise reduction ability,with the increase of width,the noise reduction ability of hedgerow gradually decreased and tended to be flat.Regression analysis showed that the noise reduction ability had a logarithmic relationship with the width.R2 was above 0.900 0.In the range of 0-2.0 m,the noise reduction ability changed rapidly with the width,and the noise reduction effect was obvious.When the width was >4.0 m,the noise reduction capacity approachedto 0,and the noise reduction effect was poor.The width of the hedge should be set within 2.0 m,and the maximum should not exceed 4.0 m.
