日照市空气质量变化特征及其与气象条件的关系
|
摘要
根据日照市2015年3月至2016年2月的空气质量日报数据以及同期气象数据,研究了该市空气质量特征及其与气象条件的关系.结果表明:日照市空气质量以II级良为主,占全年总天数的58%.PM2.5、O3和PM10为该市主要污染物;空气质量具有明显的季节特征,冬季空气质量最差,AQI的平均值为132.8,并且中度污染、重度污染和严重污染在冬季多次出现,夏季空气质量最好,AQI值为78.4;降水、风速、湿度和温度对于空气质量影响显著,大部分情况下,AQI指数与降水、风速、湿度呈负相关,与气压、气温存在正相关关系.
According to the data of daily air quality and the meteorological data of the same period from March 2015 to February 2016 in Rizhao City,this paper researches the relationship between air quality characteristics of the city and meteorological conditions.The results showed that the air quality of Rizhao City was mainly Grade II,accounting for 58%of the total number of days in the year.PM2.5,O3 and PM10 were the main pollutants in the city;the air quality had obvious seasonal characteristics.The worst air quality was in winter,with the average value of AQI 132.8;and the moderate,severe and serious pollution conditions occurred repeatedly in winter.The best air quality was in summer,with AQI 78.4;precipitation,wind speed,humidity and temperature had a significant impact on air quality.In most cases,the AQI index had negative correlation with precipitation,wind speed and humidity,and had positive correlation with air pressure and air temperature.
