摘　　要：为了评估分析枣庄市采暖季大气污染物时空变化特征及影响因素,结合地面污染物监测数据和气象数据,利用时空特征分析和相关分析法分析2018—2023年枣庄市供暖期大区污染物的时间和空间变化特征以及污染物与气象要素的相关关系。结果表明:整体上2018—2023年采暖期PM_(2.5)、PM_(10)浓度呈下降趋势;2018—2023年枣庄市污染物浓度在采暖期明显高于非供暖期,其中供暖对PM_(2.5)浓度的影响最大,其日均浓度高于供暖前157.4%;供暖期CO、NO_(2)和SO_(2)日均浓度分别高于供暖前80.3%、77.2%和26.0%;枣庄市供暖季主要大气污染物以细颗粒物为主;供暖期间NO_(2)、CO、PM_(2.5)的空间分布特征基本相同,即由中心及东南部的市中区向东北部的山亭区污染程度逐步降低;SO_(2)浓度的空间分布为东部浓度较高,向西逐渐递减;供暖期间总体上污染物与风速呈负相关,且相关性强于气温、相对湿度。In order to study the variation characteristics of air pollutants during the heating season in Zaozhuang City,combined with the monitoring data of surface pollutants and meteorological data,the temporal and spatial variation characteristics of pollutants in Zaozhuang City during the heating season from 2018 to 2023 and the correlation between pollutants and meteorological elements were analyzed by spatio-temporal characteristic analysis and correlation analysis method.The results showed that the concentration of PM_(2.5) and PM_(10) showed a decreasing trend during the heating period from 2018 to 2023.From 2018 to 2023,the concentration of pollutants in Zaozhuang City was significantly higher in heating period than in non-heating period.Among them,heating had the greatest impact on PM_(2.5) concentration,and its average daily concentration was higher than 157.4%before heating.The average daily concentrations of CO,NO_(2) and SO_(2) were higher than those before heating by 80.3%,77.2%and 26.0%,respectively.At present,the main air pollutants in Zaozhuang heating season are fine particles.During the heating period,the spatial distribution characteristics of NO_(2),CO and PM_(2.5) were basically the same,that was,the pollution degree gradually decreased from the central and southeastern city district to the northeastern Shanting district.The spatial distribution of SO_(2) concentration was higher in the east and decreased gradually in the west.During the heating period,the pollutant is negatively correlated with the wind speed,and the correlation is stronger than the temperature and relative humidity.
