We analyzed the changes of potential evapotranspiration during the past 50 years, measured as the pan evaporation in the hyperarid region. We quantified the influence of water, radiation and aerodynamic attributions of the overall trend of potential evapotranspiration in this study region and analyzed the implications to hydroclimate and water balance in this region. This phenomenon implies that the region would face to more severe water scarcity in future. We also try to demonstrate the changes in water balance in this region will be facing an accelerated or enhanced cycle which implies that the increased river discharge and evapotranspiration will cause large challenge in water resources management. Both the ecosystems and social systems will be expected to facing with severe water problems under the climate warming scenarios.
