Abstract:The main genetic processes of the soils on north slope of Bogda mountain include humification,argillization,mentle of the mountain.calcification,relic salinization-alkalization and freezing-thawing of snow The soils is weak in weathering,and have the clay minerals being dourinated by illite,and a ratio of SiO2/R2O2 of 2.84-3.54 with less difference in whole profile.The vertical distribution of soils on the mountain are of the characters of vertical soil distribution pattern in temperas desert region.There exists distinct difference in vertical soil sequence between the west and east sections of the mountain; and there are no desert soil and alpine meadow soil in the vertical soil sequence of the east section of the mountain.
