摘 要: 通过对安徽省凤阳县水泥工业区典型污染土壤剖面和水泥厂降尘的磁学参数测量,结果显示,两类样品中主要磁性矿物都是磁铁矿,土壤剖面20 cm以下样品的磁学性质由成土母质控制,磁性矿物含量较低,磁性矿物以稳定单畴和超顺磁性颗粒为主,土壤剖面0~20 cm样品由于受到水泥厂降尘影响,其磁学性质发生了变化,土壤中磁性矿物含量升高,磁性增强,磁性矿物粒度相对变粗。土壤剖面的磁学参数随深度的变化关系反映了水泥厂降尘对土壤剖面的污染过程和现状。 Mineral magnetic parameters were measured on typical polluted soil profile at the cement industry area and dustfall of cement plant, Fengyang County, Anhui Province. Results showed that the main magnetic mineral in two kinds of samples was magnetite. Magnetic properties of soil samples below the depth of 20 cm depended on the soil parent materials, showing that the content of magnetic mineral was low, and the magnetic mineral particles were dominated by the stable single and superparamagnetism. Magnetic properties of soil samples below the depth of 20 cm were affected by cement plant's dust, showing that the higher magnetic minerals, the more magnetism, and the larger magnetic minerals. The variation of magnetic parameters of soil profile with sampling depth could reflect the polluted process and situation of soil profile subjected by cement plant's dust.
