摘要

In this paper, a set of partial differential equations is established to describe the heat and moisture migration in a vegetation soil bed with an individual winter wheat growing. Steady numerical simulations have been conducted to solve the controlling equations by using the finite difference method. In order to investigate the influences on heat and moisture transport in the soil bed exerted by the plant roots, the plant coronal and the ambient conditions, comparisons between different situations that may be related to the actual cases have been carried out. Analysis and discussion have also been made to explain these phenomena.
