Characteristics and Correlation Prediction of Acoustic Environment in Functional Areas of Sichuan Province from 2012 to 2022
In order to fully implement the"Circular on Further Promoting the Nationwide Battle to Prevent and Control Pollution"issued by the State Council and to provide reference and basis for the prevention and control of noise pollution in functional areas of Sichuan Province,monitoring data of the acoustic environment quality of the functional areas in Sichuan Province from 2012 to 2022 was collected,the characteristics of the quality of the functional areas in Sichuan Province were analyzed,the grey theory was applied to analyze the influence factors of the acoustic environment quality in the functional areas,and the GM(1,1)model was established to predict the achievements at the end of the 14th Five-Year Plan in this paper.The results indicated:the control rate of acoustic environment in the functional areas in Sichuan Province has increased significantly both in day and night;and the quality of acoustic environment has improved significantly;the population,the proportion of urbanization,the number of industrial enterprises and so on were highly correlated with the acoustic environment quality of the functional areas;the accuracy of the noise prediction model established by the measured data was reliable;it is predicted that in 2025,the control rate of acoustic environment in functional areas of Sichuan Province will reach 96.5％and 83.7％respectively in day and night.As the prevention and control of noise pollution in Sichuan Province is a huge task,it is very important to prevent and control the source of noise-producing equipment,set up noise barriers on construction sites,and use environmental-ly-friendly vibration equipment and low noise pavement.
