Abstract:: In order to analyze the characteristics of temporal and spatial variation and influencing factors of actual evapotranspiration in the arid region of northwest China under the background of climate change. The Granger-Gray model(GG model)was used to estimate the actual evapotranspiration in the study area based on the meteorological observation data from 50 meteorological stations in the arid region of northwest China during 1960—2019. The spatial distribution characteristics and temporal variation trend of the actual evapotranspiration were analyzed，and the influence of meteorological factors on the actual evapotranspiration was also discussed. The results showed that:(1)from 1960 to 2019，the average annual actual evapotranspiration(ET_a)in the arid region of northwest China was about 586.9 mm，which was greater in summer and smaller in winter; ET_a was higher in the southwest and east of the study area，but lower in the northwest and central part;(2)In the past 60 years，ET_a in the arid region of northwest China showed a slight increasing trend，with a change rate of 0.24 mm/decade; ET_a increased in spring and winter but decreased in summer and autumn;(3)ET_a was positively correlated with air temperature，relative humidity and sunshine hours，and negatively correlated with wind speed，ET_a in the arid region of northwest China was mainly affected by temperature，relative humidity，sunshine duration and wind speed. In general，ET_a in the arid region of northwest China showed an increasing trend during 1960—2019，and its changes were mainly affected by temperature，relative humidity and wind speed.
