The traditional method, numerical simulation method and remote sensing method on the evaporation(evapotranspiration) study over the heterogeneous landscape are introduced and discussed in this paper. At the same time, the special role of remote sensing method on the estimation of the evaporation(evapotranspiration) over the heterogeneous landscape is also discussed. The advantages and weakness of satellite remote sensing method are summarized and the future development of the estimation of evaporation(evapotranspiration) over the heterogeneous landscape with the aid of remote sensing and field observation are discussed in the end of this paper.
