Abstract The present paper studied the light spectrum distribution, vertical attenuation coefficient, light reflection and lightabsorbance of phytoplankton in waters of the Pearl River mouth, Results showed that the attenuation of red and blue was greaterthan that of green, the intensity of green was relative great in deep water because of absorbance peak of phytoplankton at redand blue, and non-algal particle at blue and violet; radiance reflection of green was greater than that of blue and red. There wasan intensive reflection at the upper part of the water, it maybe due to greater concentration of phytoplankton.
