摘要: 近年来,我国城市臭氧(ozone, O3)污染日益严重,O3污染特征及其来源分析和防治工作引起了普遍重视。我国O3污染高值区出现在华东、华北,且污染在典型城市群聚集;污染事件主要集中在夏、秋季,冬季污染较少,大部地区O3浓度逐年上升;人为排放的挥发性有机化合物(volatile organic compounds,VOCs)和氮氧化物(nitrogen oxides,NOx)是O3污染产生的重要原因,不同区域对两者敏感性不同;高温、低湿度、低风速条件有利于O3污染维持和发展;全球气候变暖影响局地对流层O3浓度,对流层O3污染也反作用于气候变化。

Abstract: In recent years, the urban ozone (O3) pollution in China has become increasingly serious. The characteristics of ozone pollution and its source analysis and prevention work have attracted the attention of experts and scholars. This paper reviewed the research on the temporal and spatial characteristics and influencing factors of ozone pollution in China. From the perspective of O3 pollution of China, high pollution areas appeared in eastern and northern China, and O3 pollution was concentrated in typical urban agglomerations. Pollution incidents were mainly concentrated in summer and autumn, and less pollution in winter. The average concentration of ozone in most areas increased year by year, and anthropogenic emissions of volatile organic compounds (VOCs) and nitrogen oxides (NOx) were important reasons for ozone pollution, and in different regions it had different sensitivity to each other; high temperature, low humidity, low wind speed conditions were conducive to the maintenance and development of ozone pollution, global warming affected local tropospheric ozone concentration, and tropospheric ozone pollution also affected climate change.

Key words: ozone, pollution characteristics; , precursors, meteorological factors, climate change
