Reconstruction Paleoclimate Dased on Sporopollen Record of Re'nacuo Lake, Tibet

The sedimentary sequences since 33 ka B.P. to 10 ka B.P. have been established in the Re'nacuo‐Lake, Gaize area of north Tibet, through a study of a lacustrine section. The climate since 33 ka B.P. to 10 ka B.P. may be divided into two cycle include 5 dry phases and 5 moist phases from reconstructing the paleoclimate through a study of sporopollen analysis. It mainly reflects the general regularity of global climatic change through contrasting with the pale environment in northern hemisphere. Our pollen record reveals a regional climate history similar to those from the neighboring sites, including the GISP2, the Guliya ice core and core RM in Zoige, and thus supports the notion that the Qinghai‐Tibetan Plateau acts as an important link between climatic events in the North Atlantic realm and the Asian monsoon domain. The response of the Qinghai‐Tibet Plateau to the global climatic change is relatively sensitive.
