冀南地区近地面 O3浓度变化特征及其与气象因子相关性分析

摘要

以冀南地区邯郸市为研究对象，采用邯郸市环境监测站近地面O3浓度资料和邯郸市气象站同期气象资料，利用统计和相关分析方法，结合O3浓度的分布特征，对O3浓度及其与气象因素的相关性进行了分析。结果表明：邯郸市近3年以O3为首要污染物的不达标天气出现了55 d；近地面O3平均浓度以夏季最高，冬季最低；近地面O3浓度受气温、降水、风、气压等气象条件的影响，它们之间存在一定的相关性。%According to the data of O 3 concentration near the ground provided by Environmental Monitoring Station of Handan City, as well as the meteorological data in the same period from Weather Station of Handan City , adopting the methods of statistics and correlation analysis, this paper studied the distributive and change features of O3 concentration near the ground, and analyzed the correlation between O3 concentration and meteorological factors.The results showed that:in recent 3 years, O3 was the primary pollutant in Handan city, and the pollutants did not reach the standard for 55 days;the average concentration of O3 was the high-est in summer, and the lowest in winter;the O3 concentration was related to some meteorological factors, such as air temperature, precipitation, wind, and air pressure.
