%X As oasis area in Hexi corridor has more and more serious problems of wind erosion,shortage of water and heavy evapotranspiration,evapotranspiration characteristics of different tillage methods of winter wheat field and their influence factors were studied in 2005-2006. Results showed that:no-tillage with stubble retention(NTS)and no-tillage with stubble standing (NTSS) could reduce markedly soil evaporation and improve water use efficiency(WUE),and NTS was even better than NTSS.However,evaporation and transpiration under treatments with stubble cover(NTS and NTSS) was even higher than non-covered treatments(T,TIS and NT) when soil water content at layer of 0-10cm of non-covered treatments was lower than 13%.Normally,evaporation under treatments of TIS and NT was higher than covered treatments,and evaporation under T was strong in morning.Transpiration rate was,in a most significant state,positively,related with Tl,Gs and Ta and negatively related with RH.Evaporation was,in a most significant state,positively related with ST and negatively related with RH.
