摘要
基于2017—2022年安阳市臭氧逐小时浓度数据及同期气象观测资料,应用相关分析方法开展研究。结果表明,2017—2022年,安阳市臭氧污染负荷比的秩相关系数为0.943,呈显著上升趋势,年超标(74±13)d,且已成为安阳市大气环境的首要污染物;同时臭氧污染呈显著的季节性差异,夏季较重,春季次之,秋、冬季浓度较低;污染集中出现在5—9月,其中6月污染最严重;臭氧污染呈现明显的块状分布特征,污染基本呈现西部高、东部低的特点;安阳市臭氧浓度与温度和湿度的相关性较强,与日平均温度、日平均湿度的相关系数分别为0.76和-0.59。
Based on the hourly ozone concentration data and meteorological observation data of Anyang City during 2017-2022,the correlation analysis method was applied to carry out the research.The results showed that from 2017 to 2022,the rank correlation coefficient of ozone pollution load ratio in Anyang City was 0.943,showing a significant rising trend.The number of days exceeding the standard of ozone per year was(74±13)days,and it has become the primary pollutant of the atmospheric environment in Anyang City.At the same time,the ozone pollution showed a significant seasonal difference,which was heavier in summer,followed by in spring,and lower in autumn and winter.The pollution was concentrated from May to September,with June being the most serious.The ozone pollution showed obvious blocky distribution characteristics,and the pollution basically showed the characteristics of high in the west and low in the east.The correlation between ozone concentration and temperature and humidity in Anyang City is strong,and the correlation coefficients between ozone concentration and daily mean temperature and daily mean humidity are 0.76 and-0.59,respectively.
