利用建立的土壤-植物-大气连续体二维中尺度模式，模拟了绿洲与沙漠相互作用下的地表过程和能量输运特征。模拟试验的结果不仅部分用于检验和验证陆面过程观测结果，而且用于弥补观测结果的缺陷。进一步获得了土壤水分和叶片表面物理变量的日变化特征、地表能量收支的空间分布特征以及地表过程特征。在一定程度上认识到绿洲对下游沙漠的影响范围和程度。
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.
