For Huangpu river,spectral reflectivities were measured synchronously with typical water quality parameters,including total phosphor(TP),total nitrogen(TN),dissolved oxygen(DO),chemical oxygen demand with potassium permanganate(COD_(Mn)),chemical oxygen demand with cadmium(COD_(Cr)),biochemical oxygen demand(BOD_5),total suspended sediments(TSS),ammoniac nitrogen(NH_3-N) and turbidity degree(Turb).Relationships between the nine water quality parameters were analyzed.The linear relationship models were studied between water quality parameters and normalized reflectivities.The results show that there are good relationships between the normalized spectral reflectivities and the water quality parameters except for NH_3-N and COD_(Cr).If the normalized spectral reflectivities are replaced by the ratio of spectral reflectivity at different bands,the relativity will be improved,and the correlative coefficients will be more than 0.5 for NH_3-N and COD_(Cr).
