Based on systematic geochemical and synthetic analyses of oxides of the GS loesses on the northern slope of the Dabie Mountain, this paper deals with geochemical features of oxides and movement regularity of paleoclimate of this area in Middle Pleistocene.The total amount of silicon,aluminum and iron reaches 85％ in that area, and hence the authors hold that the climate has been mainly wet and hot from Middle Pleistocene till now in this area.From the distribution characteristics and movement regularity of oxides,it can be concluded that this area has experienced alternately eight times of warm and wet climate and the same times of dry and cold climate since Middle Pleistocene.Analyses of the ratios of oxides reveal that this area has experienced repeated remarkable changes from dry and cold to warm and wet,accompanied by several cycles of formation degree,eluviation and chemical weathering of soils.
