In this paper, the Bazhitou-Chaye Permian Section of Guangshun County in Guizhou Province of China is chosen as the representative section, in which five chemical stratigraphic units and seven abnormal strata were divided by the multivariate statistical analysis using 17 trace elements, As, B, Ba, Co, Cr, Cu, Ga, Mn, Mo, Ni, Pb, Sn, Sr, Ti, V, Zn and Zr of 59 layers as the variables.<BR>Through the field observation and sedimentary lithofacies analysis, two bigger sedimentary cycles and nine second-order cycles of the Bazhitou-chaye Permian Section were recognized in the light of diagenesis, color, microf acies, thickness of the layers as well as their stacking patterns.<BR>According to the comparison between chemical stratigraphy and sequence stratigraphy, the geochemical response to the Permian sea-level change and the sedimentational environments in the Upper Yangtze Platform are discussed.
