摘　　要：简要介绍了遥感监测地表蒸散和能量平衡研究的科学意义和应用价值 ,回顾了国内外的研究历史和现状 ,分析了目前该领域存在的一些问题和难点 。A review of research works concerning remote sensing of land surface evapotranspiration and energy fluxes was presented, and problems and difficulties in this field were outlined. It is pointed out that parameters retrieved from remotely sensed data are crucial for accurate simulation of land surface energy fluxes. As to the model, a two-layer representation of canopy-soil system is a good choice both for theory precision and application convenience in the field of remote sensing. The methodology of linkage between remote sensing data and land surface model is to be innovated and more remotely sensed data to be integrated in future works.
