摘　　要：为掌握嘉兴市各类功能区监测点位噪声随时间的变化情况,基于2021年嘉兴市50个功能区监测点位昼间、夜间噪声定期监测数据,以噪声小时等效声级为基础,对各类功能区噪声的年均值、小时点次超标率以及随季节变化情况进行分析和总结。结果表明,总体上,嘉兴市功能区夜间噪声比昼间噪声污染严重,1类功能区小时点次超标率高于其他功能区,夏季夜间小时点次超标率高于其他季节。In order to understand the changes of noise at monitoring points in various functional areas in Jiaxing with time, based on the regular monitoring data of daytime and night noise at 50 monitoring points in Jiaxing in 2021, and based on the hourly equivalent sound level of noise, the annual average value, hourly point exceeding rate and seasonal changes of noise in various functional areas are analyzed and summarized. The results show that, on the whole, the night noise pollution in the functional areas of Jiaxing is more serious than that in the daytime. The hourly point exceeding standard rate in class 1 functional areas is higher than that in other functional areas, and the hourly point exceeding standard rate in summer is higher than that in other seasons.
