中文摘要	Evaporation and heat transfer mechanisms differ for different types of soils. This analysis divides the Yellow River Delta soils into: bare soil, farm land and water surface based on TM data. The evapotranspiration models for the various surfaces were developed based on the surface energy balance method for the soil types. The evapotranspiration in the Yellow River Delta was then estimated based on NOAA (National Oceanic and Atmospheric Administration) data. Higher evapotranspiration rates usually occur on the Yellow River banks. The annual average evapotranspiration is 814 mm for farm land, 843 mm for marsh land, and 637 mm for bare soil. The estimated evapotranspiration for wheat and cotton is approximately equal to their water demand in 2002, which is quite consistent with the remote sensing result.
