Analysis of Ozone Pollution in Shangrao City, Jiangxi Province
摘要
为有效防治臭氧污染
分析了上饶市中心城区臭氧污染年度、季节、月份及日变化的时空分布特征
研究了气象因素、污染物(PM10、PM2.5、NO
x
等)浓度及地形和周边环境对臭氧污染的影响。研究结果表明:2017—2019年
上饶市中心城区年度臭氧质量浓度出现先降低后升高的变化趋势;在季节变化方面
夏秋季臭氧质量浓度比春冬季高;在日变化方面
臭氧质量浓度早上8:00开始升高
中午14:00达到峰值
然后逐渐下降;臭氧质量浓度受气象条件影响较大
气温较高、少云强光照、风力较低时
臭氧质量浓度较高。研究结果为上饶市中心城区臭氧污染防治、改善环境空气质量提供理论支撑。
Abstract
In order to prevent ozone pollution effectively
the time-space distribution characteristics of annual
seasonal
monthly and diurnal variations of ozone pollution in shangrao city were analyzed. The influence of the concentration of meteorological pollutants(PM10
PM2.5
NO
x
etc.)
topography and surrounding environment on ozone pollution was also studied. The results show that from 2017 to 2019
the annual ozone mass concentration in the central urban area of Shangrao first decreases and then increases. In terms of seasonal variation
ozone mass concentration is higher in summer and autumn than in spring and winter. In terms of diurnal variation
the ozone mass concentration began to rise at 8:00 in the morning
reached the p
eak at 14:00 at noon
and then gradually decreased. The ozone mass concentration is greatly affected by meteorological conditions. The ozone mass concentration is higher when the air temperature is higher and the light intensity and wind force is lower. The results provide theoretical support for the prevention and control of ozone pollution to improve the environmental air quality in Shangrao city.
