摘要

In the present paper, the spectrum response of Cyanobacter (Chlorella ulgaris) to the stress of heavy metal Pb~(2+) 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 Pb~(2+) concentration in medium. With increase of the Pb~(2+) content of Chlorella ulgaris, the spectral reflectivity in visible light and the range of red edge shift ascends, the 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 Pb~(2+) content in Chlorella ulgaris with the high squared regression coefficients of 0.8548, 0.9247 and 0.8475 respectively. The regression models are reliable to estimate the Pb~(2+) content in Chlorella ulgaris.
