摘要
就地表植被(包括庄稼、草地、裸露的土壤等)对交通噪声衰减量的影响进行研究,通过大量现场测试、数据处理与分析,建立由地表植被所引起的附加衰减量与水平距离之间更为合理的关系式,确定衰减因子α的取值,并对回归方程的精度进行检验。
This thesis researches the influence of land planting (farmland planting,grassland,bare soil etc.) on the traffic noise attenuation. By measuring on the spot, processing and analyzing of the date, the more reasonable relation has set up between the extra attenuation caused by land planting and the horizontal distance. It offers some determinate method of the attenuation factor.Finally ,the accuracy of the regression formula was checked.
