Abstract:Soil temperature regime (STR) and soil moisture regime (SMR) are two important parameters to influence soil properties and determine soil types in soil taxonomy. However, the current methods to estimate STR and SMR are not perfect, for example, hard to get real-time data, complex of calculation processes, low accuracy of estimated result, weak applicability of estimating method. In this paper, based on meteorological data and 75 surveyed-profile data in Shanxi Province, new methods were set up to rapidly estimate STR and SMR, and their application in Soil Taxonomy was discussed in order to instruct similar regional soil survey and soil taxonomy. The results showed that the new method of STE estimation was favorable in soil taxonomy, and estimated results could replace reliably measured values of soil temperature in Shanxi region. The mew method of SMR was only suitable in region without influence of ground water, while SMR of affected regions should consider actual situation of hydrological environment. However, because STR and SMR are complex and changeful in different landscapes, more and careful attention should be paid to STR and SMR determination in regional soil survey and soil taxonomy.
