Abstract: The experiment studied the relationships between biochimacal contents(Total Nitrogen, Chlorophyll, Carotenoid) and biophysical characters(Fresh Weight, Dry Weight, Moisture Content) and characteristic parameters of hyperspectra.the results showed that the correlations between all the biological parameters of leaves and characteristic parameters of spectral were good. Variables of hyperspectra were found out through stepwise regression, and the regression coefficients of equations got 0.01 siginificance level .There were good estimative effections through the examination of other tobacco leaves. As a result, the estimative models of these variables could mensurate many kinds of biological parameters quickly and without damage, so that the besement of real time inspection on tobacco field is set out by this research.

Key words: tobacco leaves, the parameters of hyperspectra, biological character, relationship
