摘要

According to the six dating data of optically stimulated luminescence, the chronology for the lake sediment since the late stage of Late Pleistocene （56.8 ka） was established, and geochemical features including sedimentary characteristic, ratio of the contents （mass fractions） of Rb and Sr, content of oxide and the ratio of them were used to reconstruct the paleoenvironmental and climatic changes since the late stage of Late Pleistocene in Bilutu. The results showed that the climatic and environmental changes since the late stage of Late Pleistocene in Bilutu were divided into five stages.
