In order to study the variation and soil formation characteristics of meadow soil properties in Xinjiang，ten representative meadow soil profiles are selected from Xinjiang，and the soil profile morphological characteristics are analyzed in detail，including soil particle composition，texture，organic matter content，total nitrogen contemt，pH，electrical conductivity，calcium carbonate and total salt contents.According to Chinese Soil Taxonomy，the diagnostic layers and diagnostic characteristics of the 10 meadow soil profiles are determined，and their attribution in Chinese Soil Taxonomy are discussed.The results show that the soil color of meadow soil in Xinjiang is mostly dark，and there is a certain degree of organic matter accumulation，but it is not strong，the weathering degree of soil is weak，and the process of meadowing is obvious.There are great differences in layer thickness，soil structure，texture，powder-to-viscosity ratio，calcium carbonate，neonatal body and diagnostic layer，and diagnostic characteristics.According to Chinese Soil Taxonomy，the 10 test soils are classified into 3 order，4 suborder，5 groups，and 7 subgroups.Based on the division of advanced taxonomic units，the basic taxonomic unit is determined which is divided into 9 soil families and 10 soil series.
