Abstract: Studying the influence of the proportion of particles constitutes on the scattering and backscattering properties, which is of great significance for development of ocean color remote parameters at each station were obtained, and correlation analysis was performed.It showed that the amplitude of the backscattering coefficients variation at each wavelength was significantly increased by the influence of the particles, and the maximum value of the coefficient of variation (CV) appeared at the band 550 nm.And the relationship between scattering(b_p), backscattering coefficients (b_bp) and total suspended particulate concentration (SPM), PIM and POM were established respectively.It was found that the water backscattering was affected by the particle composition and the concentration of organic and inorganic particles.The accuracy of the model between b_b and particle composition is higher, and the root mean square error (RMSE) varies from 0.0094 to 0.0143.The best model accuracy appeared at band 700 nm.At the same time, the effect of PIM/SPM on scattering efficiency and backscattering efficiency was analyzed.It was concluded that the backscattering efficiency Q_bbe was the mostly affected by the proportion of inorganic particles relative to the scattering efficiency Q_be.But the relevance of Q_bbe and PIM/SPM is not very high, the coefficient of determination R² is 0.4.
