摘要
在分析山东省17个地市2014—2016年的空气质量时空变化和典型城市污染天气污染物来源的基础上,发现2016年气态污染物SO_2、NO_2、CO以淄博污染最严重,威海最低;O_3浓度分布与其他污染物相反;颗粒物污染的分布表现为从西向东逐渐减少。PM_(2.5)、PM_(10)、SO_2、NO_2、CO表现为明显的季节性特征。利用HYSPLIT4模型对济南市和青岛市的污染天气的气团轨迹进行聚类分析,济南市、青岛市来自省内污染气团引起的污染天气分别占41%和64%,冷空气携带京津冀等地的污染气团南下导致的污染天气分别占59%和36%。
Air quality variance of Shandong Province from 2014 to 2016 and pollutants source analysis of pollution weather in Typical City are studied.The concentration of SO_2,NO_2 and CO in Zibo is the highest and the lowest in Weihai.Spatial distribution of O_3 is almost the opposite of others.Particulate matter concentration decreased from west to east.PM_(2.5),PM_(10),SO_2,NO_2,CO concentration show similar monthly trends.The seasonal characteristics of air pollutants are clear.The HYSPLIT4 model is used to cluster the air trajectories of polluted weather in Jinan and Qingdao.Polluted days ratios in Jinan and Qingdao caused by the air mass from Shandong Province are 41% and 64% respectively.Polluted days ratios in Jinan and Qingdao cause by the polluted air mass from Bejing,Tianjin and Hebei province are 41% and 64% respectively.
