【摘要】 文章通过选取珠三角地区具有代表性的16个树种的纯林样地,设置了10,20,30 m的林带宽度进行降噪测试,结果表明:在10 m林带宽度时,珊瑚树和高山榕的降噪效果较好;在20 m宽度,珊瑚树、白兰、环榕、竹节树和高山榕的降噪效果好;而在30 m林带宽度,白兰和高山榕降噪效果最好。3个林带宽度里降噪效果由强到弱的顺序是20 m>30 m>10m。更多还原

【Abstract】 The study was to test the Anti-noise effects of 16 representative tree species of pure woods on three different woods-widths which were 10 m,20 m and 30 m in Zhujiang Delta.By means of variance analysis method the results indicated that on reducing noise anti-noise effects of Viburnum odoratissimum,Ficus altissima were better in 10 m woods-width and Viburnum odoratissimum,Michelia alba,Ficus annulata,Carallia brachiata,Ficus altissima were better in 20 m woods-width and Michelia alba,Ficus altissima were better in 30 m woods-width.Effection of the Anti-noise of woods-width meter 20 and 30 were better and woods-width meter 20 was the best in the three different woods-widths.更多还原
