摘 要:本文通过对典型样品的低温磁行为分析探讨了磁化率反映古气候的机制,并尝试把下蜀土剖面磁化率古气候记录与华北黄土及深海沉积的记录相对比。The Xinshengwei section of Xiashu loess which was discovered recently is a more successive section near Nanjing. The magnetic susceptibility measurements of the section show that the alternation of crest and trough on the magnetic susceptibility currle of the section has close relation with the soil-loess sequence, and the cause has been probed into by the analysis of the behavior of the typical samples. The characteristic of the climatic evolution in the region has been posed by the comparison between the paleo-climatic records of Nanjing loess, Central China loess and the deep-sea sediments.
