近3 a内蒙古地区臭氧浓度时空变化及其影响因素
|
摘要
为科学认识内蒙古地区臭氧(O_3)污染特征及其影响因素,对内蒙古地区12个盟市2015—2017年国控环境监测站点和国家气象台站数据进行了分析。结果表明:2017年较2015年O_3浓度和污染形势整体上呈加重趋势,5—8月O_3浓度最高,污染最为严重,且在7月达到O_3浓度峰值。空间变化上,内蒙古中西部地区O_3污染浓度较高,东部地区O_3污染浓度较低,与内蒙古的经济发展水平表现出一定的同步性。颗粒物、前体物和气象因素等都是影响O_3浓度的重要因子,其中,PM_(2. 5)、CO、NO_2均与O_3浓度呈显著负相关,O_3浓度随相对湿度的升高逐渐下降。
In order to study the O_3 pollution in Inner Mongolia and its influential factors,the data from the national environmental monitoring stations and national meteorological stations in 12 cities in Inner Mongolia from 2015 to 2017 were analyzed. The overall O_3 pollution in 2017 was aggravated compared with that in 2015 and the O_3 concentration was the highest and the most serious during the period from May to August,especially in July. Spatially,the O_3 pollution was relatively more serious in the central and western parts of Inner Mongolia,while lower in the east parts which was synchronous with the economic development level. Particles,precursors and meteorological factors were the important factors affecting O_3 concentration. There were the significantly negative correlations between the O_3 concentration and the PM_(2. 5),CO and NO_2,and the O_3 concentration decreased gradually with the increase of relative humidity.
