This research explored the potential of the use of the CCD image of the HJ satellite to derive Suspended Sediment Concentrations （ SSC） of dynamic water bodies at Hangzhou Bay,which is a typical turbid water body in China. Through the analysis on the correlation between Remote Sensing Reflectance （ Rrs ） and SSC,two apparent reflectance peaks at approximately 690 and 830 nm have been found in the third and fourth bands,respectively. The result also shows that a good correlation exists between R rs and SSC when the wavelength is more than 700 nm. Based on the measured correlation between SSC and Rrs ,the retrieval model is established using the ratio of band 4 and band 3 as remote sensing factor,and the model determination coefficient of 0. 90 is reached. Through the Moderate Resolution Imaging Spectroradiometer （ MODIS）-derived Aerosol Optical Depth （ AOD） data,which are calculated from the Near Infrared-Short Wave Infrared （ NIR-SWIR） atmospheric correction,the atmospheric correction of HJ CCD imagery is realized. The correction-relative errors of the third and fourth bands are 5. 54% and 6. 97% ,respectively. The result demonstrates that the relative error of SSC derived from HJ CCD imagery is 7. 12% ,and SSC at Hangzhou Bay,which also has significant internal diversity,is much higher than that in the entrance of the Yangtze River. This research demonstrated that HJ CCD imagery can be used to evaluate SSC at Hangzhou Bay,if the appropriate atmospheric correction method and retrieval a lgorithm are used.
