| 英文摘要 | It is very important to develop a universal soil model with higher simplicity and more accuracy, which can be widely applied to very general cases such as wet or dry soil, frozen or unfrozen soil and homogeneous or heterogeneous soil. firstly in this study, based on analysis of both magnitude order and the numerical simulation results, the universal and simplified soil model (ussm) coupling heat and mass transport processes is developed. secondly, in order to avoid the greater uncertainty caused by the phase change term in numerical iteration process for the model solution obtaining, new version of the universal simplified soil model (nussm) is further derived through variables transformation, and accordingly a more efficient numerical scheme for the new version is designed well. the simulation results from the nussm agree with the results from more complicated and accurate soil model very well, also reasonably reproduce the observed data under widely real conditions. the new version model, because of its simplicity, will match for the development of land surface model. |
