In order to study the response of the Carnian Pluvial Episode in the southern Ordos Basin, pollen fossils, organic carbon isotopes, framboid pyrites and major elements were analyzed in Yanchang Formation in the core ZH2. Two pollen assemblages are divided as (I) Punctatisporites- Verrucosisporites-Osmundacidites assemblage and (II)Asseretospora- Apiculatisporis assemblage from bottom to top. The geological dates are the Middle Triassic Latina and the late Triassic Carnian. In the Zhangjiatan shale in lower part of the pollen assemblage (II), the total organic carbon is enriched and the organic carbon isotope has a negative drift of 4.88‰. Meanwhile, the framboid pyrites index indicates that this layer was formed in anoxia environment, and the Al2O3/MgO and CIA value are high values in this layers, indicating a high temperature, humid and enhanced weathering environment. These characteristics indicate that the Carnian Pluvial Episode had a significant impact on the Ordos Basin. Further analysis shows that these indicators can be divided into four independent high temperature, humid, anoxic and organic carbon enriched fragments in the Zhangjiatan shale, indicating four climatic fluctuations of the Carnian Pluvial Episode in the Ordos Basin, named as CPEⅠ、CPEⅡ、CPEⅢ、CPEⅣ.
