Terrestrial evapotranspiration is the key connection of a wide array of Earth system processes,which links water cycles and enemy balances over land.This paper selected 12 sensing data from NASA as the representative of four seasons,combined with the SEBS model to reckon the evapotranspiration of land surface and analyzed the ET of different land use types to verify the precision of remote sensing.To analyze the temporal-spatial characteristic,trend analysis,wavelet analysis,IDW and R/S analysis method based on Penman-Monteith wereselected.The results show that the ET in northwest of Liaoning Province decreased in the order:summerautumnspringwinter;the evapotranspriration decreased in the order:summerspringautumnwinter;the error of evapotranspiration estimating is about 7.5%in meantime,indicating that the method is reasonable to be applied in the study area.The results can provide a scientific reference for water resources allocation and management in northwest of Liaoning Province.
