| 摘 要： | 欧共体格陵兰冰芯计划（ＧＲＩＰ）中的冰芯资料揭示末次间冰期气候具有快速变化的不稳定性特征，而美国格陵兰冰盖计划（ＧＩＳＰ２）却不曾发现其不稳定证据。本文通过黄土高原诸剖面的古气候代用指标综合分析认为，末次间冰期，特别是早期气候曾出现过较大幅度的气候波动，存在不稳定性特征，支持了ＧＲＩＰ结果，表明中国黄土含有极地北大西洋的气候信息，是全球变化研究的理想记录。

| Abstract: | Ice Core information of EEC Greenland Ice Plan(GRIP) has revealed the rapid climatic change during the last interglacial age. However, no evidence of this change was found in the United States Greenland Icecap Plan (GISP2).The study of substitutive paleo climatic index from several sections in Loess Plateau suggests the existence of large climatic fluctuations during last interglacial age, especially in its early stage, which agrees with the result of GRIP. It is shown that the loess in China which contains climatic information characteristic of the polar area and the northern Atlantic provides the ideal record for global change analysis. |
