Abstract: Through establishing of volumetric weight sequences of loess-paleosols since the last interglacial in both the Luochuan section and Baicaoyuan section, and after comparing between volumetric weight, magnetic susceptibility, particle size and deep sea oxygen isotope, the authors demonstrated that the values of volumetric weight of the loess-paleosols of different climate regions at the east to west sides of the Liupanshan were different and were caused by different causes. To the east of the Liupanshan, loesspaleosols volumetric weight is controlled by East-Asian summer monsoon in semi-humid and semi-arid region and is influenced by pedogenesis,while to the west of the Liupanshan, loess-paleosols volumetric weight is controlled by East-Asian winter monsoon in semi-arid region and is influenced by particle size. Further more, volumetric weight values increase from northwest to southeast in the Chinese Loess Plateau.
Key words: volumetric weight, loess-paleosols, winter-summer monsoon, Liupanshan
