摘要
采用HS336型噪声测量仪,在自制84dB声源条件下,测定西藏校园3种单一物种植物群落桧柏、光核桃、美国黑核桃的减噪效果。结果表明:植物群落对噪声具有一定的减弱效果,不同类型的植物群落的减噪效果有较大差别,所测的3种植物群落的减噪效果依次为:桧柏>光核桃>美国黑核桃;噪声随距离的增加而衰减,在植物群落内对噪声的衰减效果更强,但该种减噪效果随声源距离的增加而逐渐减弱,所以在利用园林植物进行减噪防护时,声源点近处的植物配置要求高于声源点远处的植物配置要求。
The noise reduction effect of plant communities Sabina chinensis,Prunus persica and Juglans nigra were measured and analyzed by using HS336 in 84 dB source conditions of homemade.The results showed that plant community had certain abate effect on the noise and different types of noise reduction of plant communities had bigger difference,the noise reduction effect of the three kinds was as follows：Sabina chinensisPrunus persicaJuglans nigra;Noise had an attenuation with the increase of distance,especially in plant communities,but the effect of noise reduction weakened gradually with the distance increases.So plant configuration near sound source was higher than distant plant from the sound source in noise reduction of garden plant.
