Abstract By the field experiment,we achieve the chlorophyll concentration and reflectance of nine groups of rice leaves and investigate the quantitative relationships between them by correlation analysis.The results reveal that they have good relationship in the range of 450~686 nm and 750~770 nm, and the peak of the correlation is at the wavelength of 686nm.Meanwhile, we find strong correlation between the wavelength of the Red edge inflection point and the chlorophyll concentration of the rice leaves(R2=0.88), and then discuss the feasibility of exploring the rice chlorophyll concentration by way of hyperspectral remote sensing.
