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.
