Abstract  

The daily evapotranspiration(ET) of Central Asia and Xinjiang has been estimated from the national geostationary meteorological satellite data and ground observation for 30 years.The Surface Energy Balance System(SEBS) model can be applied in the ET estimation.Results show that the ET during the 2005 growing season in Xinjiang and Central Asia were 2 168.68×108 and 9 741.03×108 m3 respectively.The total ET for May\|September of 1980,1990 and 2005 were 8 960.64×108,9 134.37×108 and  9 085×108 m3 respectively.Through analyzing the precipitation of study area and water balance in Xinjiang,model simulation of ET is acceptable.The actual ET describes the water variation quantitatively with the participation of evaporation process and reveals the variation rules of ET process in arid areas.
