摘 要:中国城市臭氧(O_(3))污染问题日趋严重。O_(3)主要来源于汽车尾气及工业排放氮氧化合物(NOx)和挥发性有机物(VOCs)光化学反应生成,少部分来自于平流层的向下传输。文章介绍了城市O_(3)形成机理研究情况,概述了中国城市臭氧污染浓度特征及气象因子、气候变化、前体物等影响因素研究进展情况,并对未来研究方向进行了展望。The urban ozone(O_(3))pollution in China is becoming more serious recently.O_(3) arises from photochemical reactions of volatile organic compounds(VOCS)and nitrogen oxides(NOx),which is mainly released from automobile exhaust and industrial emissions,and partly from the downward transmission from the stratosphere.In this paper,the research status of urban O_(3) formation mechanism was introduced,and the research progress of urban ozone pollution concentration characteristics in China and its impact factors including meteorological factors,climate change and precursors were summarized.Finally,the future research directions and hot spots of urban O_(3) were also explored.
