PALAEOCLIMATE VARIABILITY OF THE NORTH CHINA PLAIN FOR THE LAST 120000 YEARS
华北平原十二万年以来的古气候变化

In this paper the generalized spore-pollen scheme and the temperature curve of the studied region since the Last Pleistocene are constructed based on analysis of the spore-pollen from ten drill holes, According to the climate variation, the pas t 1200011 yea rs are divided in to three s tages, seven clima tic periods, with wh-ich ten more climatic fluctuations are contained, and the overall amplitude of te-mperature changes is about 10 degrees een tigrade. The com parison of this curve with otlier tvpical climate curves in china and abroad illustrates that the I'alaco climate variability is glohal.
