%X Integrated analysis on the median grain size,CaCO3 content in the Fanjiatai loess section in upper reaches of Weihe River suggested that the climate in the Last Interglacial was characterized with warm and wet strongly influenced by summer monsoon,and that in the Last Glacial was cool and dry strongly influenced by winter monsoon.Because the summer monsoon was stronger and the deposition of dust were little during the early of the Last Interglacial(corresponding to the Stage 5e of the marine oxygen isotope records),the paleosol developed into the underlying layer;the lakes in the dust source had more water,and it induced that the grain size was little during the early of the stage MIS2 than the later;so it shows regional climatic character.
