| 摘 要： | [目的]研究临汾盆地褐土剖面磁化率与粒度垂直变化特征及相关性。[方法]在临汾市尧都区农田取120 cm深的土壤剖面,每5 cm连续采样,对所取的24个土样进行磁化率和粒度的分析。[结果]磁化率随土壤深度增加而递减,〉50μm粒级含量随着土壤深度的增加而递减,10～50、1～10、〈1μm粒级含量随着土壤深度的增加而递增。地表以下0～30 cm为砂土,30～120 cm为粉土。磁化率与1～10、〈1μm粒级含量均呈极显著负相关,与〉50μm粒级含量呈极显著正相关,与10～50μm粒级含量不相关。频率依赖系数XFD1.0与〉50μm粒级含量呈负相关,与10～50、1～10、〈1μm的粒级含量呈正相关;XFD0.1与10～50μm粒级含量呈极显著负相关,与〉50μm粒级含量呈显著负相关。[结论]磁性颗粒主要赋存于粗颗粒物质中;磁化率及粒度对沉积环境和古气候的变化有一定的响应。
