On the basis of pollen analysis of surface sample in North China, polynomial function analysis method was applied to establish pollen climate response surface of Pinus, Betula, Quercus, Artemisia, Chenopodiaceae, Compositae, Picea, Ephedra, Gramineae in North China, therefore an easy and applicable method for reconstructing palaeoclimate and palaeoenvironment with data of fossil pollen was founded; Multi-analysis method was applied to analyse the principal elements of surface sample pollen in central Inner Mongolia Steppe, the assemblages of surface sample pollen in steppe area and its relationship with vegetation type were discussed with helps from spore-pollen analysis of a peat section in Chasuqi, Inner Mongolia and 〓C chronometer, fossil pollen data were obtained with high resolution on the peat section in Chasuqi. Vegetation succession and environmental changes since Holocene at resolution of 70 years were primarily reconstructed in south Mount Daqingshan and Plain Tumete. The changes in the area were copmared with those in the neighbouring areas during the same period. It was found that Holocene environmental change had undergone the following stages: cold-arid, temperate-wet, warm-wet, temperate-arid and cold-arid, and the climatical optimum period occurred in 5000-4100 aB.
