Paleosols of China are divided into buried and relict soils.The buried soils in high-cold region of Tibet Plateau,which are characterized by compact structure,gaily colour,intensive weathering and iron-stained matrix as micromorphological feature,are mostly reserved in tills.In the arid and semi-arid regions of northwest China several layers of buried soils are found within aeolian loess sediments from early to late Pleistocene series due to deep deposition of the loess.In addition,relict soils also occur in the region.Buried soils are dominant in north part of east monsoon region,while in the south part (Qionglei region) can be found paleosols on red weathering crust.The greater changes among the paleosols in the three regions during Quaternary can be compared.
