绿化带降噪机理及模型研究进展

Research Advances in Noise Reduction Mechanism and Model of Green Belts

介绍了目前绿化带降噪机理及不同配置模式的绿化带降噪效果的研究进展。从单变量和多变量两方面总结了已有的绿化带降噪模型,普适性较差,精确性较低是目前已有模型存在的主要问题。同时,对绿化带降噪模型的研究前景进行了展望,认为可以使用非线性生态模型找出影响绿化带降噪量的主要参数,并分析主要参数与降噪量的关系,最终拟合出不同绿化带降噪量的非线性预测模型,从而指导道路绿化带的设计与建设。

The research progress on the noise reduction mechanism by green belts, as well as the noise reduction effects of green belts with different configuration modes was introduced. The current univariate and multivariate models were summarized, which were confined to poor universality and low accuracy. Moreover, the possible development in the future was predicated. The main influential parameters could be confirmed by using non-linear ecological models. According to the relationships between parameters and the amount of noise reduction, the nonlinear prediction models of noise reduction by different green belts could be fitted, which could guide the design and construction of green belts.
