摘要:
本文根据植物根系吸收土壤水分的物理过程,提出了一个既能反映根系吸水机理,表达式又相当简单的数学模型.该模型除能预报根系吸水的一些水分动态和水势动态外,还能预报有效根密度的时空变化.
Abstract:
In this paper,a simplified model of soil moisture extraction by plant roots,which can be used to account for the mechanism of soil water uptake by roots to some extent and the form of the extraction term model is considerably simple,was developed,based on the phy sical process of soil water uptake by plant roots.The model can predict not only the soil water dynamic profiles and the soil water potential profiles,but the changes of the effective root density with depth and time.
