对珠江三角洲东莞石龙、顺德容奇—桂洲两工业区的土壤磁性进行初步研究，获得两地区6个柱样及48个表层样品的磁化率（X）和天然剩余磁化强度（NRM）的结果，石龙地区的X，NRM的垂直变化平均值分别为10．86×10－6SI和6．73×10-6A·m－1，顺德容桂地区X，NRM的垂直变化平均值分别为96．84×10－6SI和31．49×10－6A·m－1，表层样容桂地区X和NRM值大于石龙地区，表明两地区土壤的磁载体存在明显的差异，磁记录大致能反映现代环境的信息。
The magnetic properties of soils in Shilong, Shunde, and Qiqihar - Guizhou industrial areas of Pearl River Delta were studied. The magnetic susceptibility (X) and natural residual magnetization (NRM) of 6 samples and 48 samples in the two regions were obtained The average vertical variation of X and NRM in Shilong region was 10.86 × 10-6SI and 6.73 × 10-6A · m-1, respectively. The average vertical variation of X and NRM in Shilong region was 96 .84 × 10-6SI and 31.49 × 10-6A · m-1, respectively. The X and NRM values of the surface Rong-Gui area were greater than that of the Shilong area, indicating that there was a significant difference in the magnetic carriers of soil in the two areas.
