摘要: 目的 分析哈长城市群臭氧(ozone,O3)的时间、空间分布特征,并结合时间因素、空间因素、气象因素和大气污染物的影响,提出哈长城市群地区O3污染防治策略及建议。方法 收集2017—2021年哈长城市群大气污染物可吸入颗粒物(inhalable particles,PM10)、细颗粒物(fine particulate matter,PM2.5)、SO2、CO、O3、NO2和气象条件(气温、气湿)数据,分析O3时空分布特征及气象因素,大气污染物对O3浓度的影响。结果 2017—2021年哈长城市群O3日最大8 h平均浓度第90百分位数(O3-8 h-P90)从133.6 μg/m3下降到119.0 μg/m3,均未超过GB 3095—2012《环境空气质量标准》国家二级标准,2017年O3超标天数最多。季节特征明显,在春季和夏季浓度高,秋季和冬季浓度低,除冬季外,其他季节均存在O3超标;月度O3平均浓度呈倒“V”型,O3浓度在6—7月份达到峰值,在1、11和12月份O3浓度最低。11个城市中O3以四平-长春-吉林为高值中心,浓度向四周辐射降低。四平市超标天数最多为102 d;11个城市中四平市的O3浓度最高,牡丹江市浓度最低。O3浓度与PM2.5、CO、NO2及相对湿度呈负相关,与气温呈正相关,差异均有统计学意义(均P<0.05)。结论 哈长城市群应该着重关注在四平、辽源和吉林市处于高温、低湿气象下的春夏季节、尤其是5—8月份O3浓度高值时段的O3防控。

Abstract: Objective To analyze the temporal and spatial distribution characteristics of ozone(O3) in Harbin-Changchun urban agglomeration,propose strategies and suggestions for O3 pollution prevention and control in Harbin-Changchun urban agglomeration on the combination of the influence of temporal factors,spatial factors,meteorological factors,and atmospheric pollutants. Methods The data of inhalable particles(PM10),fine particulate matter(PM2.5),SO2,CO,O3,NO2,and meteorological conditions(temperature,air humidity) were collected from 2017 to 2021 in Harbin-Changchun urban agglomeration,to analyze the temporal and spatial distribution characteristics of O3 and meteorological factors,and the influence of air pollutants on O3 concentration. Results From 2017 to 2021,the 90th percentile of daily maximum 8 h average concentration of O3(O3-8 h-P90) in Harbin-Changchun urban agglomeration decreased from 133.6 μg/m3 to 119.0 μg/m3,which did not exceed the national secondary standard of Ambient air quality standard(GB 3095-2012). In 2017,the number of days of O3 exceeding the standard was the highest. The seasonal characteristics were obvious,the concentrations in spring and summer were higher,while the concentrations in autumn and winter were lower. Except for winter,there were O3 exceeding standards in other seasons. The monthly average O3 concentration showed an inverted "V" shape,the O3 concentration peaked from June to July,and the O3 concentrations were the lowest in January,November and December. Among 11 cities,the O3 concentration was high in Siping-Changchun-Jilin as center,and the concentration decreased radially towards the surrounding area. The number of days exceeding the standard in Siping City was the most,which was 102 days. Among the 11 cities,the O3 concentration was the highest in Siping City and the lowest in Mudanjiang City. The O3 concentration was negatively correlated with PM2.5,CO,NO2 and relative humidity,and extremely positively correlated with temperature,and the differences were statistically significant(all P<0.05). Conclusion Harbin-Changchun urban agglomeration should focus on the O3 prevention and control in spring and summer seasons under high temperature and low humidity in Siping,Liaoyuan and Jilin,especially during the period of high O3 concentration from May to August.
