摘　　要：文章从宏观和微观两个方面扼要阐述了现代冰川过程与全球变化之间的关系。南极冰盖和格陵兰冰盖冰川物质平衡值目前还没有确切结论，虽然它与全球海平面的升降密切相关。山地冰川末端进退变化和冰川物质平衡与全球升温对应较好。极地冰盖现代降水中的稳定同位素比率，主要阴、阳离子、生物有机酸、微粒、超痕量重金属元素、宇宙尘埃以及火山灰等杂质的含量，为认识地球现代环境气候状况提供了丰富的资料。极地冰盖冰芯的分析结果为重建过去气候环境提供了大信息量，高保真度和高分辨率的资料为预测未来气候环境奠定了坚实基础，具有其它任何载体无法取代的优越性。山地冰川的现代和过去气候环境记录。In this article the relationship between the glacial processes and global change in mountain glacier and ice sheet was reviewed by the way of analysis in macroscopic and microcosmic processes. There has been no confirm results of mass balance value in Antarctic and Greenland ice sheet, although any changes in mass balance of two ice sheets result in global sea level fluctuation. It is a good response between global warming and mass balance in mountain glaciers including glacial advancing and retreating. It provides plentiful information for present climatic and environmental change by studying stable isotopic ratios, major ions, organic acids, particles, trace heavy metal elements, cosmic dust and volcanic ash etc. in surface snow and ice from ice sheet. Ice cores taken from ice sheets also provide favorable conditions to reconstruct paleo climate and paleo environment with large amount of information, high resolution and quantitative studies, which may not be substituted by other mediums. Climatic and environmental records obtained from mountain glaciers are vital in studying the situation and difference of global change and area change of climate and environment.
