Abstract：Six phytoplankton species belonging to four divisions，which may cause red tide，were selected and cultivated under different temperature(20 ℃ and 15 ℃) and illumination(7 000，4 100 and 1 100 Lux)in lab. 3D fluorescence spectra were measured in each growth period. Discrimination of these phytoplanktons’ 3D fluorescence spectra was explored using discriminant analyses. The result showed that discriminant analyses based on the principal component analysis of spectra data was an efficient method. Isochrysis galbana, Platymonas helgolanidica and Skeletonema costatuma can be discriminated effectively. Skeletonema costatuma, which is an diatom, can be distinguished from Alexandrium tamarense and Prorocentrum micans which belong to Dinophyta.
