Abstract:: The study area is the Xilin River Basin. Remote sensing approach was used to retrieve instantaneous evapotranspiration based on the estimation of land surface fluxes by using MODIS images from July 2000 to July 2014 and from Apr. to Sept. of 2000, 2007, 2010-2014, and by using auxiliary environmental data from the same time periods. Daily evapotranspiration was estimated by scaling. Monthly evapotranspiration was weighted by the number of days. Results were verified by using the FAO method. This level of uncertainty was acceptable; therefore, the method that we concluded was applicable. In the time distribution, the evapotranspiration of fifteen years from 2000 to 2014 was no fixed trend. The trend of evapotranspiration was consistent with precipitation. The maximum evapotranspiration of a year mainly occurred in June and July. The single factor correlation analysis of the monthly evapotranspiration and monthly average temperature, wind speed, relative air humidity, vapor pressure, and monthly precipitation showed that the most relevant meteorological factor with evapotranspiration is precipitation. So precipitation is the main limiting factor of evapotranspiration. Air temperature is also an important factor because of its obvious seasonal changes. But air temperature is not the main factor when it does not change obviously such as in July from 2000 to 2014.
