In this paper

the authors combine the remote sensing technique withdynamic estimating yield model

e.g.to acquire effective green index through NOAAsatellite data

estimate the index of leaf area in a certain rice unit through therelationship between green and leaf area

and estimate dried weight of each riceorgan on the basis of distributive law of rice biological quantity and the imput ofsurrounding conditions.A satisfactory simulaty effect is obtained.
