| 摘 要： | 从我国区域内筛选出于现代气候条件下发育而成的现代土壤，建立土壤颜色的红度值（x）与年降雨量（y）的函数关系式：F543．35x0.4485,其中相关系数R2=0．6625（n=25）。利用此关系式式，可根据古土壤红度值推算古降水量，为研究卉土壤与古气候定量重建提供更为精确、可靠的数据。

Quantitative Study on the Correlation between the Redness Degree in Soil Colour and Mean Annual Precipitation in China |
| |
| Abstract: | Soil profiles developed in modern climate were screened out. The function relational expression between the redness degree x of soil colour of China and annual mean precipitation y（mm） was established： y=543.35x0.448, R2= 0.662 5 （n = 25）. This relationship may be used to derive paleoprecipitation from paleosols, and provide more exact and credible data for studies in paleosols and paleoclimate quantificational reconstruction |
