摘要
In this paper, the authors present statistic results of two magnetic parameters: low-frequency and frequency-dependent magnetic susceptibility, Xlf and Xfd, of modern soil samples on the CLP and eight meteorological variables. According to the analyses, the authors developed a logarithmic MAP-Xfd transfer function (MAP=87.501×ln Xfd+360.636, R2=0.782,n=180), which is a better climofuction for paleorainfall estimates in the region with past MAP<1 000 mm.
