摘　　要：本文研究了山西土壤中锰的含量状况、分布特征及成因。结果表明,山西土壤锰含量低于全国土壤,不同亚类土壤中锰含量不同,锰含量地理分布呈东南高西北低的特征。影响土壤锰含量的因素很多,其中成土母质、气候因子中的降水量和土壤pH值的影响作用较大。Contents of manganese element in 195 soil samples collected in Shanxi were determined. The distribution of manganese and its affecting factors in soils were investigated. The results showed that the concentrations of manganese were lower than the nationwide average, the contents of manganese were diverse in different subtype soil,and the geographic distribution of manganese in the Southeast soil was higher than in the Northwestern. The parent material was a key factor controlling the distribution of manganese, the climate and texture being the second.
