摘要:

The formation of dry surface layer and its effect on characteristics of evaporation of sand dune and the evapotranspiration of grassland in the Mu Us desert are discussed in this paper. The result shows that the amount of evaporation from sand dune is dependent on the thickness of dry surface layer and soil temperature and could be calculated with a model of dry surface layer. The measurement indicates that evapotranspiration of grassland is significantly greater than that of sand dune and the average evapotranspiration of grassland is 5mm/d (summer) in the Mu Us dessert.
