摘要
以湖南省某市2015年4个国控空气自动站污染因子和气象参数监测结果为基础数据,分析了臭氧的分布特征和超标原因。结果表明,在4类不同的功能区中,工业区O_3的月均浓度和日最大8小时滑动平均浓度均为最高;O_3小时浓度的日变化呈单峰型分布,一般在8:00达到最低值,15:00达到最高值;O_3小时浓度未显现"周末效应"的特征,即工作日和非工作日的变化规律基本一致;该市O_3的生成与前体物NO_x的关系密切;O_3日均浓度和月均浓度与气温、日照时间成正比;与风速变化关系不大。
Based on the data collected by the four local state - owned automatic atmospheric observation stations from 2015, the distribution characteristics of Ozone concentration and causes for exceeding standard in the city of Hunan were analyzed. The results showed that among 4 different functional sites, the monthly average concentrations and daily maximum 8 - hour sliding average concentration of O3 in industrial district is the highest. Ozone hourly concentration variation showed a single peak distribution, the lowest appeared at 8： 00, the highest appeared at 15： 00. Ozone hourly concentration did not show ＂weekend effect＂, same variation in both work days and non - workdays Ozone production is closely related to precursor nitrogen oxides. The daily and monthly concentration of O3 was in direct proportion to air temperature and sunshine duration, while had little relationship with wind speed.
