ESTIMATION OF FLUX DENSITIES OVER THE HETEROGENEOUS LAND SURFACE WITH THE AID OF SATELLITE REMOTE SENSING AND FIELD OBSERVATION

To improve underst anding of the processes of heterog eneous land surface-atmosphere interaction, the utilization of satellite remote sensing is indispensable. The distribution charact eristics of surface heat fluxes in the heterog eneous landscape of HEIFE were analyzed with the aido fsatellite remote sensing and field obser vatio nin this paper. The results show that the reasonable regional distribution of surface albedo, NDVI and surface temperature, net radiation, soil heat flux, sensible and latent heat flux can be derived with the aid of remote sensing and the field observation. This technique is still in a developing stage, it was also discussed in this paper.
