中文摘要：

大气气溶胶的环境效应、气候效应和健康效应均与气溶胶的物理化学性质直接相关，其中大气气溶胶酸度是其重要的性质之一。大气气溶胶酸度对酸沉降、灰霾的形成具有重要作用，并影响大气非均相化学反应，相关研究已成为国际研究的热点。对国内外学者近年来在大气气溶胶酸度对大气环境与人体健康的影响、大气气溶胶酸度的影响因素与变化规律、大气气溶胶酸度／酸化缓冲能力的测定与计算方法、大气气溶胶酸性成分采集系统等方面的研究进展作了较系统的综述，并对大气气溶胶酸度研究未来的发展进行了展望。

英文摘要：

The environmental, climatic and healthy impact of atmospheric aerosol is closely related to its physical and chemical characteristics, acidity is one of the important properties of aerosol. The study on aerosol acidity has received much attention at home and aboard. Base on the comprehensive literature review, the paper presented the recent research advancements in aerosol acidity, including its influencing factors, changing rules, the determination and calculation method of aerosol acidity and the sampling system for the study of aerosol acidity. The current research status of aerosol acidity at home is simply introduced, base on which, the future direction of this aerosol acidity are put forward, such as the study on distribution and origin of aerosol acidity, the effect aerosol acidity on acid precipitation, haze, heterogeneous atmospheric chemical and the influencing mechanism.
