Abstract:

Two experiments were carried out in Shitoukoumen Reservoir on June 13th, 2008 and September 23rd, 2008 separately and some important parameters of water were measured. CDOM mainly comes from the terrestrial source in June, while the degeneration of phytoplankton in September. There is a steady inverse relationship between S and absorption of CDOM at 355nm. The ratio of CDOM absorption varies with season.

Key words: CDOM, optical properties, Shitoukoumen Reservoir, spectral slope
