对吉林省西部草地土壤化学元素含量研究表明,吉林省西部草地土壤中富钾少磷;钙、镁含量丰富;硼、铜、铁、锰含量在剖面上表现为向下增加;土壤中氮、磷、钾、钙、铜含量随草地退化程度的加深而减少;土壤中硅、钠含量丰富,显示出较强的沙化、盐碱化趋势,其含量随草地退化程度的加深而增加;钴含量随草地退化程度加深而降低;钡含量随草地退化程度的加深有增加的趋势;而稀土元素总量低于土壤背景值,并随着草地退化程度的加深其含量有减少的趋势。
The contents of chemical elements in grassland soils in the western Jilin Province show that the contents of boron, copper, iron and manganese in the grassland of western Jilin Province are increased, , And the content of potassium, calcium and copper decreased with the deepening of grassland degradation. The content of silicon and sodium in the soil was rich, showing a tendency of desertification and salinization, and the content increased with the deepening of grassland degradation. The degree of grassland degradation deepened and decreased. The content of barium increased with the degree of grassland degradation. However, the total amount of rare earth elements was lower than the background value of the soil, and the content decreased with the deepening of grassland degradation.
