Abstract: This paper deals witr the paleoclimate during the period of "Dingcun Man" by means of determination of sediments. The analyses of deposits (including differential thermal analysis, X-ray diffraction, heavy mineral, chemical analysis pH value and organic substances) and data of fossil animals and plants suggest that the climate were changeable during the late Pleistocene: from warm to cool and parched in the early stage; the same change in the middle stage; and continuing cool in the late stage.

Key words: Shanxi; "Dingcun Man"; Climate
