博格达山北坡土壤形成过程主要有腐殖质化过程、粘化过程、钙他过程、残余盐化-碱化过程、高山融冻过程。土壤风化程度低,粘土矿物以伊利石为主,粘粒SiO_2/R_2O_3为2.84—3.54,各土类差别不大,R_2O_3,沿剖面无明显移动。本区山体高大,土壤垂直分布完整,在天山北坡有代表性,并具温带荒漠土壤的垂直分布特点。土壤垂直分布东、西差异明显,西部完整,东部无荒漠土壤和高山草甸土。
The process of soil formation in northern Bogda Mountain mainly includes humus process, viscous process, calcium process, residual salinization process and alpine process. The degree of soil weathering is low. The clay minerals are mainly illite, with clay SiO_2 / R_2O_3 being 2.84-3.54. There is little difference between the soil types, while R_2O_3 has no obvious movement along the profile. The area is tall and the soil is vertically distributed. It is representative of the northern slope of Tianshan and has the vertical distribution of temperate desert soil. Vertical distribution of soil east and west differences obvious, the western integrity of the eastern desert soil and alpine meadow soil.
