Abstract: In China using pollen analysis as a researching method ’for the Quaternary has been applied increasingly.Since more then thirty years, we have had using Palynological method to expound some evidences in Paleobotany, Paleoelimate, Paleogeography, Stratigraphy and Neote-ctonics etc. But a lot of works are still limited in the level of early stage. In this paper the author- puts forward her proposals in three expects: 1. In Botany, to master the ve-getationa.1 knowledge and apply it in practice are very important. The regularities of pollen dispersal in various geographical conditions should be studied. To seek the way of the floriestic development about Quaternary in China, e.g. the problems of refuge in south China and the dry climate in north China is unfolding before us. To grasp the critical concepts about the vegetation throughly is favourable to study the environ-mental changes of the studied vegetations. However the study o’f the pollen morphology either of present or of fossils should be strengthened. 2. In the techniques of pollen analysis, to take absolute pollen will be able to raise the efficiencies of pollen analysis and rationalities of Donations, as well as the use of .numerical techniques will also be helpful. 3. In the application of the pollen analysis, to pay attention to the influence, infiltration and coordination with it’s interrelated sciences will be more beneficial. In using pollen method to demarcate the climatic period and stratigraphic subdivisions in different areas and continents should be careful.
