By the use of cluster analysis, the micro-elements of the vegetation can be sorted into 4 categories and the microelements into 3 categories. Based on the accumulated state of macro or micro-elements, the vegetation can be divided into 4 or 6 types. The chemical composition in vegetation is not directly related to the chemical composition of soils, but is closely related to the soil types and soil geochemical types. The vegetation on desert soils and saline soils belongs to Na-enriching categories, whereas Si-enriching vegetation is mostly distributed on Chestnut soils and Brown talc soils. For microelements, the ratio (Mn+V+Co+Ni+Ba+Cu)/(Sr+B+Zn+Li) is more than 1 on Brown talc soils, Chestnut soils and mountainous soils but less than 1 on flat soils; as regard of the ratio(K₂O+Na₂O)/(Cao+MgO), it is more than 1 on saline soils, but less than 1 on Siallisols and Carbonate soils, of which reaches minimum value on Carbonate soils. As for the ratio K₂O+Na₂O, it gets maximum value on Siallisols.
