摘要
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。
The paper puts forward the land hydrology coupling model of stratified soil with vegeation about land-atmosphere water and heat exchange in arid region.The physical reasons of the temperature changes and water movements stratified are analyzed, especially in the effects of the climate changes on the surface energy exchange. The restoring- force method is improved. The new computational formulae of net radiation is adopted. By using this model the numerical simuation for the water and heat processes among soil-vegetation-atmosphere in arid region near by Aksu Water Balance Station has been carried out. The result is in good agreement with observation data.
