On the basis of the remote sensing theories,we get the spectrum and the concentration,and at the same time make sure of the correlation of the data simultaneously,then work out the remote sensing reflectance of ETM+ imagery relevant to the spectrum instrument.The photoelectricity instrument works out the suspended sediment concentration. Four kinds of the experiment models are derived from the correlation of the reflectance and the concentration.The results show that the ratio of TM_4 to TM_1 has the best correlation with the concentration,therefore we can make use of the model to derive suspended sediment distribution.
