Several results have been obtained from the study on the element abundances of the grassland soil that underwent different degree of degradation in western Jilin province. First, the soil is rich in potassium and poor in phosphorus and the elements like calcium(Ca) and magnesium(Mg),as two kinds of mediocre nutrient elements, are abundant in the soil of the area. Secondly, the contents of the trace nutrient elements such as boron(B), copper(Cu), iron(Fe) and manganese(Mn) increase with the soil deepening . Thirdly, the contents of nitrogen (N), phosphorus(P), potassium(K), calcium(Ca), and copper(Cu) in the soil decrease with the degradation of the grassland. Fourthly, high silicon(Si) and sodium(Na),sometimes barium(Ba), contents are found in the soil with intensive grassland degradation while cobalt (Co) has the opposite behavior. Fifthly, the grassland soil of the region is of rare earth element (REE) content smaller than their background value and the REE decrease in content with the grassland degradation.
