Paper Abstract

On the basis of quantitative remote sensing theories, we measured the water samples of Pear River in the same zone during the flood season and the dry season synchronously by spectrum instrument and traditional way, and made sure the correlation of the data simultaneously, then worked out the remote sensing reflectance for TM imagery relevant to the spectrum instrument. The suspended sediment concentration was determined by hydrologic observation site. Eight kinds of experiment models are derived from the correlation of the reflectance and the concentration .It is concluded that the spectrum of TM3 measured during flood season correlates best with suspended sediment concentration; And the ratio of TM3 to TM2 has the best correlation with the concentration beyond the flood season. Based on the results, the results of models correspondingly with each season are better.
