%X 本文基于2016~2020年湛江市AQI、SO2、NO2、CO、O3、PM10、PM2.5的相关数据，对湛江市十三五期间空气质量指数(AQI)以及大气污染物年均浓度值变化进行分析。结果显示五年内PM2.5、PM10、SO2、NO2、CO年均浓度值均下降，AQI指数总体优良，有一定上升趋势，其中PM2.5、PM10具有“冬春高，夏秋低”的特征，SO2、NO2则呈“冬高，春夏秋低”，而O3总体呈现上升趋势，并且具有“秋高夏低”的特点；气温与六项污染物间均呈负相关性关系，相关性系数大部分较高。分析结果表明：① 在我国现行的《环境空气质量标准》下，湛江市空气质量总体较好；② O3在我国于2012年颁布的《环境空气标准中》被列入控制范围，但湛江市O3年均值总体呈现上升趋势，说明湛江市仍需加强O3生成前体污染物控制；③ 大气污染物峰值较多集中在冬季，说明湛江市应在冬季加强空气污染检测与控制。
Based on the data of AQI, SO2, NO2, CO, O3, PM10 and PM2.5 in Zhanjiang from 2016 to 2020, this paper analyzes the changes in Air Quality Index (AQI) and annual average concentrations of air pollutants in Zhanjiang from 2016 to 2020. The results show that the annual average concentrations of PM2.5, PM10, SO2, NO2 and CO all decreased in five years, AQI index is generally good, with a certain upward trend, with PM2.5 and PM10 having the characteristics of “high in winter and spring, low in summer and autumn”, SO2 and NO2 showing “high in winter, low in spring, summer and autumn”, while O3 showed an overall increase. The overall trend of O3 is rising and has the characteristics of “high in autumn and low in summer”; the correlation between temperature and the six pollutants is negative, and the correlation coefficients are mostly high. The analysis shows that: ① Under China’s current Ambient Air Quality Standards, Zhanjiang’s air quality is generally good; ② O3 was included in the control scope in the Ambient Air Standards promulgated by China in 2012, but the annual average value of O3 in Zhanjiang showed an overall increasing trend, indicating that Zhanjiang still needs to strengthen the control of O3 generating precursor pollutants; ③ The peak of air pollutants is more concentrated in winter, which indicates that Zhanjiang should strengthen air pollution detection and control in winter.
