摘要
Abstract
Noise pollution is also one of the types of environmental pollution.Based on the analysis of noise pollution levels and noise change trends of four types of acoustic environment functional zones in Nanchong main urban area from 2019 to 2021,it can be concluded that the acoustic environment quality of the acoustic environment functional zones is generally good,and the noise pollution at night is more serious than that in daytime.The acoustic environmental quality of Class 1 functional zones showed an improvement trend,but compliance rate was relatively low,and the acoustic environmental quality of class 2,class 3 and class 4a functional zones showed a declining trend.Under the influence of urban residents'life,travel,and production,the noise diurnal variation curve of each acoustic environment functional zone in Nanchong City shows a bimodal pattern overall.It is recommended to strengthen the prevention and control of nighttime noise pollution in the main urban area of Nanchong City in the future.关键词
