英文摘要	Much sediment is transported into Bohai by Yellow River every year. Therefore the study on suspended matter concentration(SPM) in Yellow River estuary is significant to the environmental monitoring and sediment transport of surrounding ocean. The piecewise linear retrieval model was proposed based on the remote sensing reflectance and suspended matter concentration synchronous sampled in summer and winter in 2011. The results showed: the sensitive bands combination for suspended matter concentration inversion was different under different concentration ranges, (600 similar to 700 nm) /(400 similar to 600 nm) and (750 similar to 900 nm)/(420 similar to 720 nm) respectively to the concentration range below and above 50 mg . L-1 , and the corresponding bands for Landsat 8 OLI were B4/B2 and B5/B3 respectively. The R-2, RMSE and APD of the Piecewise model were 0. 873 5, 4. 08 mg . L-1 and 22. 81% (SPM <= 50 mg . L-1) , 0. 969 3, 102. 96 mg . L-1, and 17. 51% (SPM>50 mg . L-1) respectively, and 0. 975 3, 67. 03 mg . L-1 and 20. 45% for the overall concentration, which were better than parameters of common single model under entire concentration range. In summary, the piecewise linear retrieval model is more suitable for suspended matter concentration inversion of the Yellow River estuary with large variation of concentration.
