摘要 Depositing ages of sediment in core CK6 of Qarhan Salt Lake were determined by usingmethods of ^(14)C, ^(230)Th and paleo-terrestrial-magnetism. Based on synthetic analyses for thevariation of the content of organic carbon, sporo-pollen composition and lithofacies, the fluc-tuating model of paleo-climate since 750 ka B.P. was set up. It is divided into 21 fluctua-ting epochs of climate, among them, 11 are warm and humid epochs, and 10 are dry andcold epochs.
