柳州市交通主干路绿化带降噪服务功能研究
|
摘要
通过对柳州市9条主干路绿化带的生态结构调查和噪声测定,分析了全乔型、乔灌型、全灌型、全草型等4种典型绿化带类型的降噪效果,并通过公式计算得出绿化带的降噪功能量及价值量,研究其生态效益.结果表明:(1)道路绿化带对柳州市交通噪声有一定的降噪效果;(2)不同类型绿化林带对交通噪声的降噪效果不同,乔灌型最佳,全草型最差;(3)9条主干路各类型绿化带降噪功能量为269186.57 dB/a,降噪总价值量为1996933.02元/a,其中,乔灌型营造模式占总量的69.72%,有最大的降噪价值,全草型仅占总量的0.41%;(4)东环大道、柳石路、柳太路、桂中大道绿化带总体降噪效果较好,最差是屏山大道.
As the link between the city and the countryside,the traffic noise pollution affects the urban image and the physical and mental health of the residents along the route.Through monitoring the noise level alongside the green belts along the urban trunk roads in Liuzhou,the differentiations of noise reduction effect among all arbor,arbor+shrub,all shrub and all grass have been studied,and the noise-reduction service and value by green belts of suburban road are calculated by formula.The results showed that(1)The green belts has a certain noise reduction effect of traffic noise in Liuzhou;(2)green belts can reduce traffic noise to some extent to meet the standard requirements,but different configurations have different noise reduction effect,and the all arbor was the best and the all grass was the worst;(3)the noise-reduction service and value were 269186.57 dB/a and 1996933.02 yuan/a alongside the green belts along the urban trunk roads in Liuzhou,and the arbor+shrub that is 69.72% of the total has the maximum noise reduction value,and the all grass is only 0.41% of the total.(4)noise-reduction of the green belts along the Dong-Huan road,Liu-Shi road,Liu-Tai road and Gui-Zhong road are better,and noise-reduction of the green belts along Ping-Shan road is the worst.
