| 摘 要： | 冰岩芯研究是古气候、古环境研究的有力手段,它将为“全球变化研究”提供多方面的气候、环境信息。在冰岩芯研究中,通过稳定同位素(δ18O或δD)、放射性10Be、微粒含量变化、冰结构变化、CO2含量变化、CH4含量变化、各种化学元素含量的变化等多种手段建立了两极地区倒数第二次冰期以来气候、环境及大气成分演化的大概轮廓。

| Abstract: | Ice core study, providing much information for "a study of global change", is an effective approach to the study of paleoclimate and paleo-environment. The study of climate and environment in ice cores was carried out mainly by analyzing stable isotope (δ18O or δD), 10Be, microparticle concentration, ice crystals and fabric, CO2 and CH4 concentrations, chemical elements and so forth.The ice core study being carried out so far has revealed a basic picture for the changes in climate, environment and atmosphere since the penultimate glaciation. |
