摘 要：
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 5, 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
