This study discusses the validation between explorations of transpiration on the unsaturated soil zone with unsaturated flow equation of tree water uptake model. Numerical simulation was performed to the model of the slope in relation to moisture migration patterns in the unsaturated zone within the vicinity of mature tree. The results of numerical simulation conducted on typical slope geometry model with tree at the toe of the slope of induced transpiration were later presented in this study. The results of numerical simulation and field monitoring of suction against depth are in acceptable condition. It is important to note that, several of the differences between simulated numerical and field measurement are related to inconsistence effect of root density.

本研究利用树水吸收模型的非饱和渗流方程，讨论了非饱和土壤带蒸腾作用的验证。对与成熟树附近的非饱和带中水分迁移模式有关的坡度模型进行了数值模拟。稍后在该研究中介绍了在典型的坡度几何模型上用树在诱导蒸腾坡度的脚趾处进行的数值模拟结果。吸力对深度的数值模拟和现场监测结果处于可接受的条件下。重要的是要注意，数值模拟和田间测量之间的一些差异与根系密度的不一致效应有关。
