%X Quaternary was divided into Pleistocene and Holocene according to standard in China. The former was divided into three stages. Most geologists treaded them as three series. Quaternary is four-division. We present following advice. (l) Quaternary is generally divided into two series-Pleistocene and Holocene in the world. Quaternary researchers of China are used to divide Pleistocene into Lower-Pleistocene, Middle-Pleistocene, Upper-Pleistocene. Considering of the status quo of Quaternary research, national economic construction and study on global changes, we suggest that it is more suitable to consider rather 'Lower-Pleistocene', 'Middle-Pleistocene', 'Upper-Pleistocene' as series than stages. However, the division of series and the stages is global tendency, and the division of Quaternary still needs to be discussed further. (2) According to chronostratigraphy, the boundary between Lower-Pleistocene and Middle-Pleistocene is located at B/M boundary (0.78MaB.P.); on the basis of petrostra- tigraphy and biostratigraphy of Nihewan Formation and Wucheng Formation, the Q2/Q1 boundary is dated at l.00-l.20MaB. P. (3) According to chronostratigraphy, the boundary between Middle-Pleistocene and Upper-Pleistocene is located at 0.128MaB.P., which stands for the beginning of last interglacial, according to petfostratigraphy and biostratigraphy of paleosol S1 at Loess Plateau, Salawusu Formation and Xiaodukou Formation, the Q3 / Q2 boundary may be alternative in 0.128MaB.P. or 0.14MaB.P. or 0.20MaB.P. (4) The boundary between Upper-Pleistocene and Holocene is mainly about 0.010-0.011MaB. P., which represents the end of glacial and the beginning of thermomer.
