冰雪层是记录全球变化的主要信息载体之一，其中由生源要素碳形成的杂质种类最多。总结了这些含碳杂质记录古气候和古环境变化方面的研究进展，涉及温室气体、低分子可溶性有机酸、人为有机污染物以及孢粉和高碳数有机质。讨论了今后这些研究的重点所在。

关键词: 冰雪层, 含碳杂质, 气候变化, 环境变化

Ice and snow layers are the main information recorders for global changes. The widespread carbonaceous im purities exist in three states of gas, liquid and solid in the layers. The paper summarizes the development of the studies on these carbonaceous impurities for climatic and environmental im plications. The following impurities are discussed as greenhouse gases, high soluble organic acids with low molecular weight, organic pollutants from activities of mankind, spores and pollens, and organic matter with high carbon numbers. Some important study trends on the impurities are presented.

Key words: Ice and snow layers, Carbonaceous impurities, Climate change, Environment change.
