Wang Yanyi(Institute of agricultural modernization, Academy of agricultural Sciences of Jiangsu )  
This paper introduces the reletionship between rice production and paddy field spectrum data, it indiCates that:Before rice full-head emergence, the correlation coefficient between ratio vegetation index(RVI)and rice growth (Leafarea index or dry biomass) is extremely high, and a good numerical measurement relation exists between them.After this stage, the correlation coefficient between RVI and dry biomass is remarkable.The correlation coefficient between PVI (standardded perpendicular vegrtation index )and rice yield components (ear numbers per Mu, full grainumbers per ear and the weights of one thousand grains) as well as theoretical rice yield are extremely high. Between them there is a good numerical measurement relation.
