内容 研究概要:The processes of evaporation on the ground in Dongkemadi River Basin near the Tanggula Pass were observed with weighting-lysimeter method from May to September 1993, and some preliminary results were got. Evaporation mainly occurred from May to September and the daily mean soil evaporation in July is higher than in other months; there is a nice linear relationship between the soil evaporation and water evaporation which observed in 20 cm evaporation pan; the soil evaporation is much influenced by ground surface water content; that varied not only with the change of the water content, but also with water content self; the evaporation processes are influenced by topography through changing climatic parameters and the conditions of supplying water on the ground surface, as evaporation process is stronger in the fine days, the soil evaporation at the top is higher than at the bottom for a slope; the daily process of soil evaporation for different ground surface conditions is quite different. Comparing to the west of the Plateau, the soil evaporation in the center of Tibetan Plateau is few. The annual soil evaporation is estimated to be about 300 mm.
