摘　　要：回顾了关于长距离输送对中国区域本底大气臭氧的影响,以及中国区域大气本底站臭氧变化及其区域代表性两方面的研究进展。来自不同污染源区O_(3)的长距离输送对中国区域O_(3)影响的研究结果分歧较大,贡献最显著的源区和受体地区也存在争议;同时,鲜有研究考虑到平流层对对流层的O_(3)贡献,而这部分贡献在前体物排放很少的本底地区非常重要。中国区域各大气本底观测站分别与其周围一定范围内的区域具有相同的对流层O_(3)柱浓度最大值月份分布,而对与人体健康密切相关的近地面O_(3)区域特征的分析尚未深入开展;鉴于研究方法的局限性,也尚未深入揭示形成O_(3)变化区域特征的复杂成因。基于现有研究进展和不足之处,如何利用全球大气化学-环流模式的示踪模拟结果,定量评估来自全球不同地区的O_(3)对中国本底大气O_(3)的影响,并进一步评估中国区域6个大气本底站近地面O_(3)季节变化的区域代表性,是亟待解决的科学问题。The influence of long-distance transport on atmospheric background ozone and the variations in ozone and its regional representativeness at atmospheric background stations in China are reviewed.Studies results on the impact of long-distance transport of ozone from various pollution sources on ozone in China are quite different,and the source and recipient regions with the most significant contribution are also controversial.In adddtion,few studies have considered the ozone contribution from the stratosphere to the troposphere,which is of significant importance in the background regions with few precursor emissions.Each atmospheric background observation station in China has the same maximum monthly distribution of tropospheric ozone column concentration with the surrounding areas in a certain range.However,the analysis of the surface ozone region characteristics significantly related to human health has not been carried out.In view of the limitations of the research methods,the complex causes of the regional ozone variations have not been deeply revealed.Based on the current research progress and deficiency,the scientific problems to be solved include making use of the source-tagging results of global atmospheric chemistry-circulation model to quantitatively determine the contributions of ozone originating from various regions of the world on the atmospheric background ozone,then evaluating the seasonal variations in surface ozone its regional representativeness at the six atmospheric background stations in China.
