气候变化对环境空气质量影响的研究进展

Advances in the Effect of Climate Change on Air Quality

  • 摘要: 回顾了国内外气候变化对环境空气质量影响的相关研究成果。已有研究表明,气候变化可以通过改变地面气温而加速某些大气污染成分(如O3)的前体物(如VOCs)的自然源排放,可以通过改变化学反应速率、边界层高度和天气系统出现频率等来影响污染物的垂直混合和扩散速度,还可以通过改变大气环流形势,进而改变污染物的传输方式;气候变化不仅影响到室外空气质量,还可以影响室内空气质量,给人体健康带来威胁。因而,气候变化可以影响局地或地区的大气环境质量,也可以带来室内空气质量的改变,这些认识已被学者们达成一致。但是这些影响仍存在着诸多不确定性因素,主要包括:未来气候变化的趋势和程度,未来的大气污染物及其前体物的排放量,大气污染成分与气候变化因子间的相关关系,不同大气组分间在不同气象条件作用下的物化过程和机理的认识等。我国在涉及气候变化对环境空气质量影响研究方面处于起步阶段,建议今后加强该项研究,尤其是在气候变化对与空气质量相关的公共健康影响方面的研究。

     

    Abstract: The current understanding about the effects of climate change on air quality is reviewed. It has been found that the increase of surface air temperature can accelerate the natural source emission of the precursors(eg. VOCs) of some air pollutions (eg. O3); it can change the vertical mixing and diffusion rate by modifying the chemical reaction rate, the height of Planetary Boundary Layer (PBL), and the occurrence frequency of weather systems; it can also alter the atmospheric circulation and thereby change the manner of pollution transport. Climate change can affect not only the outdoor air quality but also the indoor air quality, hence there might be a threat to human health. Thus, climate change can impact the regional or local outdoor and indoor air quality, on which most scholars have reached an agreement. However,these impacts still have some major uncertainties: The trend and intensity of future climate change, the future emission of air pollutions and their precursors, the correlation between atmospheric pollution and climate change factors, and the physical and chemical mechanisms of atmospheric constituents in the diverse meteorological conditions. The topic on the effect of climate change on air quality is still at the initial stage in China. Therefore, the authors suggest discreetly that the research projects on this topic, especially, on the impacts of climate change on airpollutionrelated public health, should be launched in China.
