中文摘要:
      重点对河北省辛集市"十三五"期间整体空气质量变化情况以及影响辛集市优良天数的2个重要参数O3和PM2.5的污染规律进行了分析。结果表明,辛集市"十三五"期间空气质量改善明显,优良天数整体增加,污染天数整体减少。O3浓度及其作为首要污染物出现的天数整体呈现上升趋势,对综合指数的贡献率逐年增加;O3污染高发期主要集中在4—9月,高值区域分布差距较大,但市区污染持续突出。PM2.5浓度逐年下降,以PM2.5为首要污染物的天数逐年减少;PM2.5浓度季节变化特征整体呈现"秋冬高、春夏低"的分布特点,空间分布呈"南北高、中间低"的污染特征。
英文摘要:
      This paper focused on the analysis of the overall air quality changes in Xinji City during the 13th Five-Year Plan period,and the two essential indicators of O3 and PM2.5 that affect the good air quality days in Xinji City.The results showed that during the 13th Five-Year Plan period,the air quality of Xinji City had improved greatly,the number of days with good air quality had increased,and the number of polluted days had decreased as a whole.The concentration of O3 and the number of days when O3 appeared as the primary pollutant showed an upward trend,and the contribution rate of O3 to the composite index increased year by year.The periods with high incidence of O3 pollution were mainly from April to September.The spatial distribution of high O3 value was different,but the pollution in the urban area continued to be prominent.The concentration of PM2.5 and the number of days with PM2.5 as the primary pollutant decreased year by year.The concentration of PM2.5 showed a clear seasonal variation with high values in autumn and winter and low values in spring and summer,and the spatial distribution showed the pollution characteristics of "high in north and south,low in the middle".
