湖南省“十三五”城市声环境质量状况与趋势分析

为综合评价全省城市声环境质量状况,进一步探讨城市声环境存在的问题。该文收集2016—2020年湖南省14个城市声环境质量监测数据,并进行趋势分析。结果表明,2016—2020年湖南省城市声环境质量得到逐年改善,但夜间达标率相对较低;14个市州城市功能区声环境夜间达标率为71.4%~74.8%;区域声环境质量总体保持较好水平,社会生活噪声仍是主要声源;道路交通声环境质量稳中向好,但一定比例路段存在超标现象,城市环境噪声污染治理值得重视。

In order to comprehensively evaluate the quality of urban acoustic environment in the province,the existing problems of urban acoustic environment are further discussed.In this paper,the monitoring data of acoustic environment quality in14 cities in Hunan Province from 2016 to 2020 are collected,and the trend is analyzed.The results show that the quality of urban acoustic environment in Hunan Province has been improved year by year from 2016 to 2020,but the rate of reaching the standard at night is relatively low.The rate of reaching the standard at night in the urban functional areas of 14 cities is 71.4%~74.8%.The overall quality of regional acoustic environment remains at a good level.Social living noise is still the main sound source.The quality of road traffic sound environment is stable and improving,but there is a phenomenon of exceeding the standard in a certain proportion of road sections,so more attention should be paid to the control of urban environmental noise pollution.
