摘要
漳州城市建设和工业飞速发展,汽车数量剧增,人为大气污染排放显著增加,空气质量下降,对人们的生活和健康造成了影响。本文利用2014—2015年连续2年的日平均污染数据,选择主要污染物SO2、NO2、O3、PM10、PM2.5和AQI指数,分别与日平均气温做相关分析,研究发现:SO2浓度在不同季节与温度的相关不同,这是由于气温与SO2的清除机制没有直接关系,因此相关不确定;NO2浓度与气温基本呈负相关,而O3的浓度呈正相关。秋季影响当地空气质量的主要气象条件是气温,当气温高于25℃时,空气质量改善明显。
Analysis of air pollution feature in Zhangzhou from 2014 to 2015 found that air quality was mainly affected by changes of particulate matter, followed by SO2, NO2, O3, PM10, PM2.5 and AQI.The heaviest pollution occurred in winter while the lightest pollution in summer .The studies of impacts of meteorological conditions on air pollution found that AQI index , particulate matter , NO2 and SO2 negatively correlated with air temperature , while the concentration of O 3 was positively correlated .The main factor affect-ing air quality is temperature in autumn , when the temperature is higher than 25℃, the air quality improved significantly .
