Fluorescence excitation-emission matrix spectroscopy was employed to characterize the change of humic-like fluorescence from Dagu River to Jiaozhou Bay. The relationships of humic-like fluorescence characteristics with salinity, pH, chlorophyll a, dissolved organic carbon, chemical oxygen demand and carbohydrate were discussed. The results show that humic-like fluorescence intensities are high in Dagu River but low in Jiaozhou Bay. The input of Dagu River is important origin of humic-like fluorescent dissolved organic matter of Jiaozhou Bay. High humic-like fluorescence intensity and high chlorophyll a are not coexist always, which suggests that humic-like fluorescent dissolved organic matter doesn't mainly come from phytoplankton. Good relationships of humic-like fluorescence intensity with dissolved organic carbon, chemical organic demand and carbohydrate suggest that humic-like fluorescent matter is the main component of dissolved organic matter. The distribution of humic-like fluorescence reflects the distribution of dissolved organic matter to some extents.
