Abstract
Carbon isotopic compositions of organic matters in the sediments during late Glacial Maximum and Late Glacial Period have been analyzed in arid semiarid areas of northwestern China. It shows that the sediment have recorded in detail the process of climatic oscillation that changed from dry and cool to warm and wet in thousand or hundred years scale during this period in the transition of monsoon edge belts. High resolution record of organic carbon isotopic compositions is the same as that of GRIP oxygen isotopic composition. It also indicates that there is a relative climatic changes between the globe and arid China. The climate was warm and wet in the transition period of late Glacial Maximum to Late Glacial, and terrestrial plants grew briskly. And the monsoon had taken an important action in the climatic oscillation in Shiyang river basin. The proxy of δ 13 C is the effective indicator of reconstructing the palaeoclimatic variation in the arid China because of its sensitivity to the climatic changes.
