| 摘 要： | 通过黄土高原及其临区１０４个地点地表土壤磁化率值与当地的现代多年平均降水量的回归分析，建立了磁化率与降水量的转换函数。在遍布黄土高原不同地区典型的全新世黄土－古土壤剖面磁化率测量的基础上，利用所建立的转换函数，初步恢复了全新世气候适宜期，黄土高原及黄土／沙漠过渡区年降水量的分布状况。

| Abstract: | Through regression analysis on the magnetic susceptibilities of surface soils taken from 104 locations in loess plateau and adjacent areas and the contemporary multi-yaer mean rainfall,asusceptibility-rainfall conversion function was established. Based on the determination ofsusceptibilities of typical Holocene loess- paleosol profiles in different areas of the loess plateau andusing the conversion function established, the suitable climatic period of Holocene and the rainfalldistribution of the loess plateau and loess-desert transitional areas were preliminarily reconstructed. |
