摘要
Based on the grain-size analysis of the paleosol section at Fenghuang Mountain in Chaoyang, Liaoning Province, the percentages of the coarse grains, fine grains and supper-fine grains were used as indicators of winter monsoon, westerly wind and summer monsoon strengths, respectively. The results show that the winter monsoon, westerly wind and summer monsoon change synchronously. The winter monsoon has the opposite variation trend. The climate was warm and wet at the following stages: 71～148, 176～208, 225～243, and 311～403 B.P., and the climate was cold and dry at the following stages: 148～176, 208～225, 243～311, and 403～423 ka B.P..
