摘要
根据中山市4个空气质量自动监测站的监测数据,统计2009年全市O3、NOx的浓度值及气温、日照值。分析了它们的变化趋势和O3与相关因素的相关关系。结果表明O3、NOx的浓度值及气温、日照值有明显的季节和日变化规律,O3与NOx浓度有较好的负相关性,O3浓度与气温、日照有很好的正相关性,相关水平达到0.9以上。
According to the four automatic air quality monitoring station in Zhongshan City of monitoring data, statistics in 2009 the city O3 density.NOx density.temperature and sunlight intensity value in there. Analyses the change trend and the correlation between O3 and related factors. Results show that O3 density.NOx density.temperature and sunlight intensity value have significant seasonal variation and daily variation, the concentration of O3 and NOx is good negative correlation, O3 concentration and temperature. sunlight intensity value is very good positive correlation, the correlation levels reached more than 0.9.
