摘　　要：植物不仅满足视觉观赏体验,还可以吸尘降尘、降温加湿、吸收有害气体以及优化周围声环境。分别在福建农林大学中华名特优植物园和福州市温泉公园中选取具有代表性的6种植物群落,对其不同高度、不同宽度以及不同配置的植物群落对噪声的衰减效果进行综合比较分析,以探究最佳的优化声环境的植物配置方式。结果表明:竹林的减噪效果最佳,其次是乔灌草型、乔草型、灌草型和灌木型,草坪型减噪效果较弱;较高的植物群落对噪声的衰减作用更强,延续性更久;盖度越大的植物群落对声环境的优化效果越好。Plants can not only meet the visual experience,but also can dust down,cool down,absorb harmful gases and optimize the surrounding sound environment.Attenuation effects of different height,width & arrangement of six representative plant communities on noise were compared in the famous botanical garden of Fujian agriculture and Forestry University and Fuzhou Hot Spring Park;plant arrangement mode to optimize the sound environment was explored.Result shows that the descending order of reduction effect for noise is bamboo>trees,shrubs and grass>trees and grass,>shrubs and grass>shrubs;reduction effect for noise of grass is weak;higher plant communities have stronger attenuation effects and longer continuity on noise;the greater coverage of plant communities have the optimization effect on the noise environment.
