%X 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.
