摘要: 大气降水化学是大气化学的重要组成部分,是评估人类活动对大气环境影响的可靠指标,而且保存在高海拔地区雪冰中的化学成分对研究局地和全球气候环境变化以及环境演变过程具有重要意义。中国西部冰冻圈地区的大气降水化学研究始于19世纪70年代末,目前已取得一些重要进展,特别是结合积雪和冰芯化学的研究获得了大量的降水化学资料。回顾了中国西部冰冻圈地区大气降水化学的研究背景,综述了该领域取得的主要研究成果并对其研究前景进行了展望。

Abstract: Atmospheric precipitation chemistry is a credible indicator describing the anthropogenic influence on atmospheric environment. Chemical compositions in snow and ice in high-elevation regions play an important role on environmental change on regional and global scales and its evolution process. Precipitation studies in cryosphere regions of western China began in the late 1970s, and many results have been achieved, in particular those about precipitation data obtained from snow cover and ice core. This paper reviewed the research history and major results of precipitation chemistry in China. In addition, it is necessary to establish long-term and systemic monitoring stations that represent regional precipitation characteristics combined with the Global Atmospheric Observation Network, China Acid Rain Observation Network, and the observation stations of Chinese Academy Sciences, and it is important to collect snow cover and ice core samples to supplement dataset of precipitation chemistry in high-elevation regions. Moreover, we should strengthen studies on trace element, organic acid, POPs and so on in precipitation based on the advanced-analysis technology (mass spectrum, gas chromatography-mass spectroscopy and the like) to supply more evidences to anthropogenic influence. Furthermore, it is also necessary to attach importance to the present-process research of atmospheric aerosol-snow cover-ice core, which plays an essential role in establishing a spatial distribution model of atmospheric precipitation chemistry in the cryosphere regions of western China.
