This paper briefly introduced the“China Quaternary Pollen Database”(CPD), its organization, protocols, data-submission and share of the major contributions for its all members using the pollen data from CPD , as well as the world-wide collaborative project“Biome 6000”supported by IGBP and focusing on biome(vegetation) reconstruction of modern(0 ka BP), Middle Holocene(6 ka BP) and the Last Glacial Maximum(18 ka BP) based on full-documented pollen data and biomazation procedure. Biome patterns of mentioned time slices for China constructed from CPD are showed and important difference of 6 ka and 18 ka BP biome patterns from modern one in China are discussed also in this paper.
