摘要：

A new core, GPXX, from La Grande Pile (Vosges, France) has enabled a more precise evaluation of pollen data concerning the last climatic cycle at this site and has enabled reconstruction of the monthly temperature and precipitation. This paper shows that the various components of the reconstructed climatic signal are clearly separated and that they are coherent with the vegetation dynamics. The Eemian interglacial was influenced first by an oceanic climate and second by a more continental one. The two interstadials, St-Germain I and II, were mainly continental. These three temperate periods ended with a cool and humid transition period dominated by boreal forests, which may have been favourable to ice accretion. The Dansgaard-Oeschger oscillations from 55 to 25 Kyr BP are not significantly recorded in La Grande Pile.
