| Abstract: | The last interglacial, Marine Isotope Stage 5 (MIS 5, about 71~128 ka BP), is the closest to modern interglacial period, in which there are identifiable patterns that could give us clues into what will happen in the future. Pollen analysis, the study of fossil pollen and spores, is one of the key methods for the reconstruction of past vegetation and environment. Pollen data from 23 sites in eastern Asian region were reviewed to document regional patterns of vegetation and climate change during MIS 5 and to understand the large-scale controls on these changes. The regional patterns of vegetation during MIS 5 can be compared with the present-day vegetation. The climate, inferred from pollen record, was not stable during MIS 5. The substages (5a, 5b, 5c, 5d and 5e) of MIS 5 can be identi?ed by pollen assemblages in some areas, which describe the imprint of orbital-scale climate oscillations. East Asian monsoons have significantly contributed to the environment of modern eastern Asian monsoon region during MIS 5. However, the climate in Japan is also affected by the ocean currents and westerly circulation. The climate of the Tibetan Plateau is controlled by interactions of competing factors, including Indian monsoons, westerlies, and topography. In eastern Asian region, particularly in arid and semi-arid regions, the high-resolution pollen records need to be further studied for the better understanding of the climate change. |
