To improve understanding of the processes of heterogeneous land surface - atmosphere interaction, the utilization of satelli te remote sensing is indispensadle. in this paper, with the aid of satellite remote sensing and fiend observational data which observed during intensive observation of huaihe river bain energy and water cycle experiment hubex in 1998, the surface albedo, ndvi normalized difference vegetaton index and surface temperature in regional scale of hubex could be derived. then, the distribution of regional energy balance components could be estimated. this wor provided the physical foundation for the numerical simulation of the huaihe river basin energy and water pro cesses, and is important for us to further analyze the regional distribution of surface characteristic parameters ad energy balance components with the change of the weather situation in hubex in 1998. our work is still in a developing stage, some methods of retrieval in the paper should be improved further
