Abstract

In the present paper, the spectrum response of rice leaf to the stress of heavy metal Zinc pollution was studied in three spectral ranges of the red edge position (REP) (680-740 nm), the visible spectrum (460-680 nm) and the near infrared spectrum (750-1000 nm). The results indicate that the chlorophyll level reduces with the increase of Zinc concentration in soil. With increase of the Zinc content of rice leaves, the leaf spectral reflectivity in visible light and the range of red edge shift ascends, the leaf spectral reflectivity in the near infrared light decreases. The visible light, the near infrared light and the range of red edge shift are fitted much linearly with the logarithm of Zinc content in rice leaves with the high squared regression coefficients of 0.9182, 0.9477 and 0.9445 respectively. The regression models are reliable to estimate the Zinc content in rice leaves.
