摘要
2015年,O38 h已成为泸州市第二大污染物。统计发现,2015年5-8月间O3浓度较高,其它月份则较低。O3浓度呈现单峰型分布,峰值出现在15：00至17：00,未出现所谓的“周末效应”,周末O3浓度与工作日差异不大。水平分布上,O3表现为市区低,郊区高的特点。NO、NO2和NOx等前体物多呈现双峰型分布,其中,NO和NOx与O3均呈显著的负相关性,相关性在春季最高。对比阴晴天气条件下O3浓度的日变化发现,光照强度是影响近地面臭氧浓度的另一主要因素。
In 2015, O3_8 h has become of O3 was higher in May to August in 2015, the second largest pollutant in Luzhou. It was found that the concentration and lower in the other months. O3 concentration showed a single peak distribution, the peak appeared in the 15：00 to 17：00, the so-called ＂weekend effect＂ was not appeared, at weekend, O3 concentration showed no difference to working days. In horizontal distribution, O3 performance showed low at urban and high at suburbs. NO, NO2 and NOx showed bimodal distribution, among them, NO and NOx were negatively correlated with O3, and the correlation was highest in spring. The diurnal variation of O3 concentration in sunny weather indicated that light intensity was another major factor affecting near-surface ozone concentration.
