摘　　要："十三五"期间,佛山市环境空气质量总体改善。从时间变化上看,SO2、PM10和CO(95per)浓度五年内持续达到国家环境空气质量年二级标准,其中SO2和PM2.5浓度呈明显下降趋势;"十三五"末年(2020年)与"十二五"末年(2015年)相比,佛山市SO2、NO2、PM10、CO(95per)和PM2.5浓度均出现下降,但O3-8h(90per)浓度出现上升;PM2.5作为首要污染物发生频率呈明显下降趋势,但O3-8h作为首要污染物发生频率却呈明显上升趋势。从空间分布上看,佛山市五区SO2、NO2、PM10和PM2.5浓度均有所下降,仅高明区CO(95per)和O3-8h((90per)浓度出现上升。During the "13th Five-Year Plan",the air quality in Foshan improved on the whole.The concentrations of SO2,PM10 and CO(95 per) continued to meet the national standard for environmental air quality in five years,and the SO2 and PM2.5 showed an obvious trend of decline.Compared with the end of the "13th Five-Year Plan"(2020) and the end of the "12th Five-Year Plan"(2015),the concentration of SO2,NO2,PM10,CO(95 per) and PM2.5 in Foshan decreased,but the O3-8 h(90 per) increased.The occurrence frequency of PM2.5 as the primary pollutant showed an obvious decreasing trend,while the O3-8 h showed an obvious increasing trend.In terms of spatial distribution,the concentrations of SO2,NO2,PM10 and PM2.5 decreased in the five districts of Foshan,while the CO(95 per) and O3-8 h(90 per) increased in Gaoming district.
