摘要
对土壤水分运动的滞后效应(包括水分特征曲线、导水率的滞后效应)、植物体内水分传输的滞后效应的形成机制、数学模型、对SPAC内水流运动的影响及该领域研究的新课题等,作了述评。
The hysteretic effects which have been discovered and studied in the soil-plant-atmo-sphere continum are the moisture characteristics ,the hydraulic conductivity characteristics and therate of water flow in plant-water potential relationships. The actual phenoma of cosiderable hystere-sis characterizing the hydraulic conductivity-capillary head relationships,and the less significant hy-draulic conductivitv-moisture content hysteresis,is proposed.The theories and predicting models ofhysteretic effects are reviewed in this paper.The problems and new taskes are discussed at last.
