【英文摘要】On the basis of the Nam Co Obeservation Station of ITPCAS, we use multi-proxy to study the physical properties of Nam Co sediment core since Holocene, in order to study the variation of environmental process on time and space scale and to reconstrust the standard climate curves of Holocene in Tibetan Plateau. In addition, for comparision we also study the lacustrine core of Pumoyum Co since 19 ka cal BP and the ice core of Ningjingangsang since 1852 AD. Then we compare the curves with the ice cores from the Greenland and Antarctica, providing constrain on the impact on global climate changes by Tibetan Plateau.
