<正> The NOAA is a special meteorological satellite. The first and second channels of the AVHRP (the sensor of NOAA) are much similar to the fifth and seventh channels of the resource satellite MSS
and their corresponding spectral response curves are much alike. The AVHRR’S first channel has a higher reflectivity from soil
and the second channel is highly reflected by vegetation. By virtue of its wide sensitivity range

We established a servies of green models which can be need in making agricultural estimation satisfactorily.As expesimentally showed that these green models highly correlated to the yeild of crops. This has been presently becoming the main information sources for yield estiraatings. With the forecast of the yield of winten wheat is Tianjin are as an example
this paper gave an account of the application of the NOAA/AVHRR data in working out the yeild estimation It included the establishment of the regression equation and the method for calculating the plantation area.
