本研究提出了干旱区陆气水热交换中包含植被效应的土壤分层陆地水文耦合模型,分析了数学模型中温度变化与水分运动分层的物理原因和气候状况对地表面能量交换的影响,改进了强迫恢复法,采用了新的计算净幅射的计算公式,最后利用本模式,对新疆塔里木盆地阿克苏水平衡试验站干旱区的土壤、植被、大气间水热交换过程进行了数值模拟,模拟结果与实测值重合较好。
In this study, the soil stratified terrestrial hydrological coupling model with vegetation effect in the air-water heat exchange in arid area was proposed. The physical causes of the temperature change and the stratification of water movement in the mathematical model and the influence of climate conditions on the surface energy exchange were analyzed. Forced recovery method, using a new formula for calculating the net radiation. Finally, this model is used to simulate the process of water-heat exchange between soil, vegetation and atmosphere in Aksu water balance station in Tarim Basin, Xinjiang. The simulation results Coincidence with the measured value is better.
