摘要:

通过对位于不同气候带的北京、禹城和桃源3地的全年空气孢粉采样以及表土尘孢粉采样的研究分析,初步了解代表暖温带、中亚热带的现代花粉雨的组成,其中空气孢粉组合较表土尘孢粉组合更能反映区域植被的成分;区域花粉雨特征可以作为气候带划分的标志;我国东部花粉雨分析还表明,花粉的远距离迁移与东亚季风气候关系密切,花粉的迁移路线反映了季风运行的轨迹。通过花粉雨的研究,进一步了解孢粉组合—植被—气候三者的联系,将有助于应用孢粉分析恢复植被、恢复气候的定量研究

Abstract:

Composition of modern pollen rains representing warm temperate and central Asia tropic zones has been obtained based on analysis of the year round aerial pollen samples and pollen samples in surface soils from Beijing, Yucheng and Taoyuan which are located in different climatic zones. Of them aeropollen assemblage can better reflect regional vegetation composition in contrast to surface soil pollen assemblages, and characteristics of regional pollen rain can be regarded as a mark to classify climatic zones. Analysis of pollen rain from eastern China also indicated that long distance pollen migration is closely related to East Asia mosoon, and pollen migration route reflects the trajectory of monsoon activities. Studies of pollen rain made it possible to further understand the relationships of pollen composition-vegetation-climate which will be helpful to conduct quantitative analysis on rehabilitation of vegetation and climate by means of pollen research.

Key words: Eastern China, pollen rain, implication of study
