吕梁市城区环境噪声监测与分析 在吕梁市世纪广场和宏泰广场附近进行噪声监测，通过监测数据分析噪声污染源，减少噪声污染，保护吕梁市声环境。通过现场监测和计算监测点的等效声级，对测得数据进行汇总，利用Surfer13绘制噪声分布图。 监测数据显示，吕梁市的世纪广场和宏泰广场两个区域的噪声污染非常严重。36个监测点的监测数据均超出标准，最高监测声级为104.7dB，超标74.5%。与2017年世纪广场的监测数据对比，污染程度升高。利用Surfer13绘制了白天与晚上的噪声分布图，图中显示白天的噪声源主要是路边店铺的商业活动噪声和交通干道上的机动车产生的噪声，广场上聚集的广场舞活动和秧歌是主要噪声源。等效声级最大为96.9dB，超标61.5%。 噪声控制应从噪声源控制、传播途径、城市管理几个方面着手。另外公安、城管等有关部门要密切配合，做好区域环境噪声治理，改善城市声环境，共同建设美丽新城。 关键词：噪声污染；噪声监测；噪声治理 Abstract Noise monitoring is carried out around Century Square and Hongtai Square in Luliang City to analyze noise pollution sources through monitoring data, reduce noise pollution and protect the sound environment of Luliang City. Through site monitoring and calculating the measured data are summarized and the noise distribution map is drawn using Surfer13. Monitoring data show that the noise pollution in Century Square and Hongtai Square, two areas of Luliang City, is very serious. The monitoring data of 36 monitoring points all exceeded the standard, and the highest monitoring sound level was 104.7dB, 74.5% above the standard. In contrast with the 2017 Century Square monitoring data, the pollution level has increased. The map draws the noise distribution between day and night with Surfer13. The picture shows that the noise sources during the daytime are mainly the noise from commercial activities in roadside shops and the noise generated by motor vehicles on the traffic road. The square dance activities and Yangko dance gathered in the square are the main noise sources. Max. The equivalent sound level is 96.9dB, Over the standard of 61.5% . Noise control should start from noise source control, transmission path and urban management. In addition, the public security, urban management and other relevant departments should work closely together to do a good job in regional environmental noise control, improve the urban sound environment, and jointly build a beautiful new city.
