摘 要: 综述了未来50~100年人为排放变化和气候变化对臭氧(O3)全球总量和区域O3空气质量的影响及其机制。在不同未来排放情景的驱动下,全球O3总量将呈现不同幅度的上升,美国、欧洲等发达地区的人为源减排将降低本国的地面O3浓度。气候变化带来的水汽浓度上升将减小全球地面O3背景浓度。但在污染地区,地面O3的夏季平均浓度和高污染O3发生频率及强度都将呈现上升趋势,目前此类研究主要集中在发达国家。考虑到我国未来人为源排放的快速增长趋势和气候变化的显著特征,研究排放和气候变化对我国区域O3空气质量的影响具有重要意义。

Abstract: The previous studies on the impacts of anthropogenic emissions and climate change in the future 50-100 years to the global ozone budget and regional ozone air quality were reviewed in this paper. Driven by different future emission scenarios, global ozone budget would increase at a different scale. Domestic emission reduction in developed regions such as U.S. and Europe reduced surface ozone in these areas. Climate change alone would decrease background surface ozone, driven by higher water vapor. However, the summertime surface ozone in polluted regions would increase as well as the frequency and magnitude of pollution episodes. The regional ozone air quality studies had mainly targeted in the developed countries. Concerning the rapid increasing emissions and climate change for China in the future, it was important to investigate the effects of parallel changes in emissions and climate on China�s ozone air quality.
