Abstract： It is of great significance for scientific management and efficient utilization of water resources in the basin to deeply explore the information of internal conversion process of land use types, measure the impact of land use change intensity on evapotranspiration, and accurately evaluate the temporal and spatial variation of ET. Based on the intensity analysis model, the intensity change characteristics of land use types at different levels in the Aksu River Basin from 2000 to 2020 and their impact on the actual evapotranspiration of the basin were revealed. The results showed that : ( 1 ) At the time interval level, the intensity of land use change in the basin increased first and then decreased, and the change was the most active from 2000 to 2005. At the land type level, the increase and decrease of cultivated land, construction land, water area and forest land area are more active. The increase of cultivated land area at the transfer level mainly comes from grassland ( 54.31% ) and unused land ( 26.26% ). ( 2 ) The average annual evapotranspiration of the basin is 166.56 mm. The interannual fluctuation is large, and the overall trend is increasing, with an annual growth rate of 3.68 mm·a-1. Evapotranspiration from April to October accounted for 71.76% of the annual evapotranspiration. The high value of actual evapotranspiration is distributed in mountainous forest land and cultivated land in plain area, and the low value area is distributed in piedmont desert area and oasis and desert transition zone. ( 3 ) The results of principal component analysis show that the driving force of ETa change in Aksu River Basin is the conversion intensity of grassland, cultivated land and unused land. The correlation coefficient between land use change intensity and actual evapotranspiration is 0.87, and there is a strong correlation between the two.
