中国第四纪孢粉数据库(CPD)和生物群区(Biome 6000)

“CHINA QUATERNARY POLLEN DATABASE” (CPD) AND “BIOME 6000” PROJECT

介绍了中国第四纪花粉数据库的建立、组织及数据收集、大型成果共享等原则及章程，并着重介绍了当前由ＩＧＢＰ所支持的用孢子花粉资料重建６ｋａＢＰ及１８ｋａＢＰ生物群区（植被）的全球合作项目。到目前为止，利用中国第四纪花粉数据的原始数据及生物群区化方法已经完成中国现代表土花粉、６ｋａＢＰ（中全新世）及１８ｋａＢＰ（２０ｋａＢＰ）（末次盛冰期）的生物群区模拟及重建，在文中展示了制图结果，并讨论了当时植被与现在相比的重大差异。

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.
