摘要
根据描述ＳＰＡＣ系统蒸腾蒸发及土壤水热状况的物理模型，导出了反映群丛蒸腾蒸发与土壤水热状况互为作用的冠层湿温方程，提出了能定量描述二者耦合关系，并能同时求解二者的耦合迭代法．经检验，该方法模拟结果可靠．
Based on the physical models describing the evaporation-transpiration on SPAC and the water-thermal conditions of soil, the humidity-temperature equation of the canopy reflecting the coupled relation between the evaporation-transpiration from the foliage and the water-thermal conditions of the soil is deduced. A coupled iteration method that can be used to quantitatively depict the coupled relation and to solve the evaporation-transpiration from the foliage and the water-thermal regime of the soil simultaneously is developed. The reliability of this method is verified by experimental result.
