In this paper, the trends of pan evaporation and actual evaporation are investigated using observational data and observation-constrained simulation results using NCAR Community Land Model (CLM) in Xinjiang from 1960 to 2005. The results suggest
that decrease of pan evaporation indicates an increase of actual evaporation in Xinjiang in the past half century. The correlation analysis shows that diurnal temperature range, wind speed, low cloud cover and precipitation are the most likely driving forces
