摘　　要：广安市地处四川省东北部,也是四川省距离重庆市最近的城市,将广安市打造成为川渝合作示范区的成效与当地综合环境质量息息相关。以广安市为研究区,统计2021—2022年区域噪声、功能区噪声和道路交通噪声监测数据,分析声环境质量特征,以明确噪声源。结果表明,区域声环境质量总体稳中有降,其中一级噪声覆盖的区域面积减少趋势比较明显。功能区昼间噪声均可实现100%达标,夜间噪声2021年全部达标,2022年达标率为87.5%。2021年道路交通昼间噪声达标率为100%,2022年道路交通昼间噪声环境质量有所下降,达标率为85%。总体来看,广安市声环境质量的主要噪声源是社会生活噪声和道路交通噪声。Guang’an city is located in the northeast of Sichuan province and is also the closest city to Chongqing city,and the effectiveness of building Guang’an city into a demonstration zone for Sichuan province-Chongqing city cooperation is closely related to the overall environmental quality of the local area.Taking Guang’an city as the research area,the monitoring data are collected on regional noise,functional area noise,and road traffic noise from 2021 to 2022,the characteristics of sound environment quality are analyzed,and the sources of noise are clarified.The results indicate that the overall quality of the regional acoustic environment has remained stable with some decline,with a more significant decrease in the area covered by first level noise.The daytime noise in the functional area can achieve 100% compliance,and the nighttime noise all met the standard in 2021,with a compliance rate of 87.5% in 2022.The compliance rate of daytime noise in road traffic in 2021 was 100%,and in 2022,the environmental quality of daytime noise in road traffic had decreased,with a compliance rate of 85%.Overall,the main sources of noise in the sound environment quality of Guang’an city are social life noise and road traffic noise.
