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
