Abstract: | Biomization provides an important way to assign pollen taxa to biomes and to simulate palaeo-vegetation patterns, so that
pollen data can be mapped to reconstruct biogeography and climate. The authors have tested the applicability of this procedure
to assign modern pollen surface samples from China to biomes. The procedure successfully delineated the major vegetation types
of China. When the same procedure was applied to 6 ka B. P. fossil pollen samples, the reconstructions showed that the forest
zones were systematically shifted northwards ca. 300–500 km beyond their present northern limits in eastern China; the area
of desert and steppe vegetation was reduced compared to the present in northwestern China; the area of tundra was reduced
largely on the Tibetan Plateau. This research is a contribution to the project of BIOME 6000 in Pacific-Asian regions.
