Theoretical and experimental studies of the growth and development of tree and shrub vegetation are determined by sorption characteristics, which depend on the moisture content in capillary-porous materials of phytomass stands. Thermodynamic parameters of mass transfer and their gradients are of fundamental importance. The purpose of this theoretical study was to solve a scientific problem on the development of theoretical foundations for mathematical modeling of mass transfer of moisture and nutrients in the vascular system of growing wood material, taking into account the energy potential. The research provides a theoretical justification and consideration of the thermodynamics of moisture mass transfer in the capillaries of wood materials. Based on the study of thermodynamic driving forces in capillary-porous growing wood bodies, it is established that the mass transfer potential is the chemical potential, which in the vascular system of wood and bast depends on free and chemically-bound moisture. The equations of filtration effect of moisture and moisture gradients on the mass transfer of moisture in capillary-growing wood materials, given the thermodynamic potential in non-isothermal conditions for wood phytomass, depending on the rate of change of thermodynamic potentials.

乔木和灌木植被生长发育的理论和实验研究是由吸附特性决定的，吸附特性取决于植物群毛细孔材料中的水分含量。传质的热力学参数及其梯度至关重要。本理论研究的目的是解决一个科学问题，即在考虑能量潜力的情况下，为生长木材的血管系统中水分和养分的质量传递数学建模建立理论基础的科学问题。该研究为木质材料毛细管中水分传质的热力学提供了理论依据和考虑。基于毛细孔生长木体的热力学驱动力研究，已经确定传质势是化学势，它在木材和韧皮的血管系统中取决于自由和化学结合的水分。考虑到木材植物体在非等温条件下的热力学势，取决于热力学势的变化率，水分和水分梯度对毛细生长木材中水分传质的过滤效应方程。
