Evapotranspiation retrievals in conditions of rugged terrain and arid/semiarid sparse vegetation are always the hotspot in estimation of regional evapotranspiration from remote sensing images. Concerning with the complex characteristics of the loess hilly-gully region, such as undulating topography, un-unique land use/covers and less vegetated land surface, etc,land surface characteristic parameters and flux was retrieved, and the instantaneous veg-etation transpiration and soil evaporation was estimated with the TSEB parallel model by using the Landsat TM da-ta for an experimental study site located on the conjuncture area of Shaanxi and Gansu where the terrain surface is very undulating with less vegetation developed, heavy soil and water loss loess plateau. And then the calculated re-sult was merged into daily evapotranspiration, also the spatial pattern of the daily evapotranspiration was analyzed.Actual evapotranspiration of the study area was calculated with the extra resistance method and Penman-Monteith equation to compare with the TSEB parallel model estimated, which suggested that the TSEB parallel model can be used for the accurate estimation of evapotranspiration in loess hilly-gully region.
