摘要
扼要回顾中国南极冰川学研究历程、当前国际南极冰川学研究背景和发展趋势,并从南极冰盖雪冰物理特征研究、冰盖气候环境记录的现代过程研究以及冰芯研究等方面总结我国南极冰川学研究取得的成果认为80年代后期以来,中国南极冰川学研究成果显著,尤其是对南极冰盖气候环境记录的现代过程研究取得了很大进展。
The history of Antarctic glaciology in China is reviewed with the emphasis on the past decade Much progress has been made both in investigation of physical characteristics of the Antarctic ice sheet and caps and in study of climatic and environmental records in Antarctic snow and ice Through the observation of snow profiles of numerous snow-pits and shallow cores over Wilkes Land and Lambert Glacier basin and along the route of the 1990 International Trans-Antractica Expedition (ITAE), regional features of snow deposition and densification over Antarctica were revealed The Nelson Island ice cap in South Shetland Islands was investigated in detail, which has enriched knowledge of glaciers in sub-Antarctic maritime climate From shallow ice core study and chemical analyses of surface snow samples, in particular those taken along the ITAE route, most systematic data has been obtained for distribution of stable isotopes, soluble impurities and heavy metal Pb in modern precipitation over Antarctica After discussing the international hot pots at present and the trend in near future, some suggestions are proposed
