摘要
用新发展的二维中尺度土壤－植被－大气连续体数值模式（陆气耦合模式），系统地模拟了绿洲与荒漠相互作用下的陆面特征和地表能量输送特征。这一模拟结果不仅部分地验证了陆面过程野外实验的观测结果，而且还弥补了野外实验的不足，进一步得到了土壤水分和植被叶面物理量的日变化特征及大部分陆面特征量和地表能量收支平衡的空间分布特征，对绿洲影响其下游沙漠的程度和尺度范围也得到了一定程度的认识。
Using the developed two-dimensional mesoscale model of soil-plant-atmosphere continuum, the characteristics of land surface process and energy transport under interaction of oasis and desert are simulated. The results of the simulation test are not only used partly to test and verify the observational results of land surface process, but also to remedy the defects of the observation results. The diural variation of soil water and physical variables of leaves surface, the spatial distribution of surface energy budget, and the characteristics of land surface process are further obtained. The range and extent of the influence of oasis on the downstream desert are recognized to a certain extent.
