Abstract: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.
