以北欧 Austre Okstindbreen 冰川为例,概括介绍了海洋型气候区温冰川内气候环境信息的主要特征山地温冰川积雪中的环境记录, 如氧同位素、阴阳离子含量的变化虽然受到了冰雪中的融水渗透的干扰, 但仍可作为短期局部气候环境变化的理想指示器通过与实测的气象气候资料对比, 积雪中化学分析结果表明了若干重要特征: 积累区雪层剖面中的氧同位素变化, 较好地反映了本地区的气候变化特别是降水时的温度递变细节以及降水量和气温之间的关系,并且清楚地指示出从雪- 粒雪- 冰川冰的转变过程而雪剖面中的阴阳离子,则较多地反映了降雪时较大尺度的大气环流变化、降水来源和途径、大气污染事件等同时这些化学成分在雪层中的分布状况,也显示了融水渗透等因素对其的影响状况和程度
Taking the Austre Okstindbreen glacier in northern Europe as an example, the main characteristics of climatic and environmental information in the warm glacier of the oceanic climate zone are summarized. Environmental records in the snow cover of the mountain glacier, such as changes in oxygen isotopes and anions and cations, However, it can still serve as an ideal indicator of short-term local climate change. Comparing with the observed meteorological and climatic data, the chemical analysis results in snow cover show several important characteristics: the oxygen isotope Changes, which better reflect the details of the temperature changes in the region, especially the precipitation, as well as the relationship between precipitation and temperature, and clearly indicate the transition from snow-snow-glacier ice to snow The positive and negative ions in the profile reflect the larger-scale atmospheric circulation changes, precipitation sources and pathways, air pollution events and the like at the same time. The distribution of these chemical components in the snow layer also shows that the infiltration of melt water And other factors affect the status and extent
