For studying on the regional land surface heat fluxes over inhomogeneous landscape of the Tibetan Plateau area

the utilization of satellite remote sensing is indispensable.In this study

methods based on NOAA-14 AVHRR and Landsat TM are introduced and tested for deriving the regional land surface variables

vegetation variables and surface heat fluxes over inhomogeneous landscapes of the GAME/Tibet（GEWEX（Global Energy and Water cycle Experiment） Asian Monsoon Experiment on the Tibetan Plateau） area and the CAMP/Tibet（CEOP（Coordinated Enhanced Observing Period） Asia-Australia Monsoon Project（CAMP） on the Tibetan Plateau） area.Difficulties on the determination of regional land surface heat fluxes over heterogeneous landscape of the Tibetan Plateau by using the methods are introduced and the solving way to the difficulties is also proposed in this paper.
