Paper Abstract

Chlorophyll-a of Chlorella vulgaris had been related with spectrum. Based on hyperspectral measurement for Chlorella vulgaris, the hyperspectral characteristics of Chlorella vulgaris and their optimal hyperspectral quantitative models of chlorophyll-a (Chla) estimation were researched in situ experiment. The results showed that the optimal hyperspectral quantitative model of Chlorella vulgaris was Chla=180.5+1125787(R700)'+2.4 *109[(R700)']2 (P0<.01), and the suitability order of corresponding methods was spectral ratio<single band < reflectance first-derivative. According to hyperspectral characteristics of Chlorella vulgaris, two reflectance crests were around 540 nm and 700 nm and their locations moved right while Chl-a concentration increased. The reflectance of Chlorella vulgaris decreases with Cha concentration increase in 540 nm, but on the contrary in 700nm.
