极地冰芯包含了大气循环的各种信息,微粒作为其中一个重要的参数,在揭示古环境和古气候信息中起着很重要的作用。冰芯中微粒的含量变化可用于年层的划分,矿物和粒径特征可以用于源区以及大气本底值的研究。另外,微粒记录中还包含了火山、沙尘暴以及人类活动等特殊事件的信息。在过去的 50年间,在几大冰芯研究的基础上,极地冰芯微粒的分析工作已取得了很大的成果。近年来,得益于测试水平的迅速提高,微粒研究工作有了长足进展。展望未来,人们将会开拓更新的研究领域。
The polar ice core contains all kinds of information about the circulation of the atmosphere. Particles as an important parameter plays an important role in revealing paleoenvironment and paleoclimate information. The change of the particle content in the ice core can be used for the division of the layers. The mineral and particle size characteristics can be used for the study of the source area and the atmospheric background. In addition, particulate recordings contain information on specific events such as volcanoes, dust storms and human activities. Over the past 50 years, based on several major ice core studies, great efforts have been made in the analysis of polar ice core particles. In recent years, thanks to the rapid increase in test levels, great progress has been made in particle research. Looking to the future, people will explore newer areas of research.
