摘　　要：对近几年在土壤—植物系统中瞬态流理论方面的研究成果，如电模拟模型、时间“常数”的变性、水容及相对重要性、水流阻力的大小及相对重要性、水流阻力的变性和水分运动的滞后效应等问题进行了介绍和综述。The achievements of theory of unsteady water flow in the soil plant system that have been researched by us during recent years are introduced, which are electronic simulated model, the changes of the time constant, hydraulic capacitances and their relative importance, hydraulic resistances and their relative importance, variability of hydraulic resistance and the hysteretic effect between water flow and water potential difference in the soil plant system.
