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。

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 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 |
