摘　　要：森林是陆地生态系统重要的组成,且在全球碳循环中发挥着重要作用。本文对东北及邻区末次冰盛期以来的森林面积进行重建。首先,根据71条孢粉序列计算了乔木化石孢粉的百分比;然后,根据孢粉点位的乔木化石孢粉含量进行克里金插值,预测东北及邻区的乔木化石孢粉含量;最后,提取点位的预测值与实际值进行对比检验插值的可靠性。该插值方法可以应用于东北及邻区乔木化石孢粉数据的插值。Forests are an important component of terrestrial ecosystems and play an important role in the global carbon cycle.This paper reconstructs the forest area since the last glacial maximum in Northeast China.Firstly,the percentage of pollen in tree fossils was calculated according to 71 pollen sequences.Then,the pollen content of tree fossils in Northeast China was predicted by Kriging interpolation according to the pollen point.Finally,the reliability of the interpolation is tested by comparing the predicted value with the actual value.This interpolation method can be applied to the palynological data of tree fossils in northeast China.
