| 摘 要： | 采用野外磁测和室内分析的方法，对广东省主要成土母质和土壤类型的磁性变化以及土壤有机碳与磁化率的关系进行了研究。结果表明，不同母质和土壤类型的磁性差异很大，其磁化率的大小顺序为：玄武岩母质＞花岗岩母质＞石英岩母质；砖红壤＞赤红壤＞水稻土。旱作土有机碳与磁化率具极显著正相关，而水稻土有机碳与磁化率具极显著的反相关。

| Abstract: | Measurement of the magnetic properties in the field and laboratory analysis were adopted for studying the magnetic variation of the main rocks and soils.andthe relationship between organic carbon and mangetic susceptibity in Guangdongprovinee.the results showed that the magnetic susceptibility of each rock and soil typewas very different,the order of magnetic susceptibility being basalt>granite>quartzite,laterite>lateritic red earth>paddy soil.The magnetic susceptibility showeda significantly positive correlation with the organic carbon of dry land,and asignificantly negative correlation for paddy soil. |

| Keywords: | basalt granite quartzite laterite lateritic red earth paddy soil orga nic carbon magnetic susceptibility |
