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.

本文在对中国北方表土花粉研究的基础上,采用多项式函数回归方法建造了中国北方松属、桦属、栎属、蒿属、藜科、菊科、云杉属、麻黄属、禾本科等的花粉——气候趋势面,从而为利用化石花粉资料直接恢复古气候、古环境提供了一种方便易行的方法;采用多元分析方法对内蒙古中部草原区表土花粉进行了主成分分析,探讨了草原区表土花粉组合的规律及与植被类型的关系;本文还应用孢粉分析方法,结合〓C测年技术,通过内蒙古中部察素齐泥炭剖面高分辨率的化石花粉数据,初步恢复了大青山山地南部及土默特平原地区分辨率为70年的全新世以来植被演替和环境变迁的状况,并与邻近地区的全新世古气候、古环境进行了对比研究,研究发现,本区域全新世古环境的变迁序列基本上可以与周围地区及华北地区进行对比,其环境变迁经历了凉干~温湿~暖湿~温干~凉干的变化,且气候最适宜期出现在5000~4100aB.P。
