2011—2015年泉州市空气质量变化及典型污染天气分析
|
摘要
利用2011—2015年泉州市空气质量自动监测数据,对大气污染物的变化趋势进行分析。结果表明:2011—2015年泉州市空气质量总体保持良好;SO2年均浓度呈显著下降趋势,NO2浓度于2012年开始呈缓慢上升趋势,PM10年均浓度变化趋势于2013年开始呈显著下降趋势;SO2和NO2月均浓度无明显的变化趋势,O3月均浓度变化呈凹字形, PM10、PM2.5和CO月均浓度较高值和较低值分别出现于1月—5月和7月—9月;各空气污染物浓度均呈现春冬高、夏秋低的趋势;静稳天气对空气质量有较大的影响,是污染天气发生的主要原因。
Based on air automatic monitoring data of Quanzhou, the variations of air pollutants were analyzed. The results showed that the air quality from 2011 to 2015 of Quanzhou stayed clean. The annual concentration of SO2 showed a downward trend while the annual concentration of NO2 rising slowly from 2012. The annual concentration of PM10 had significant downward trend from 2013. There was no significant variation for monthly concentrations of SO2 and NO2 while the monthly variation of O3 was concave. The monthly concentrations of PM10, PM2.5 and CO were high between January and May while low between July and September. All the pollutants were high in spring and winter but low in summer and autumn. Stable weather had big influence to air quality and it was the main reason that caused pollution.
