Abstract

The spectral reflectance was measured with hand-spectral instrument in Hangzhou Bay, and the water samples were collected in situ and analyzed in the lab. The relationships between chlorophyll-a (CHL) and total suspended matter (TSM) and the measured spectral reflectivity were analyzed, and CHL and TSM concentrations were estimated by using the combination of the field bands and TM image, respectively. The Empirical algorithm and Bio-optical model were applied to analyze the chlorophyll and total suspended matter horizontal distribution in Hangzhou Bay wetland. Comparison of the Empirical algorithm, the bio-optical model were selected and the models have higher precision, which would be validated for the estimation of CHL and TSM content by using the TM images. Finally, the two estimation models were discussed to educe the estimation models. Two of the most precise ones were used to estimate the CHL and TSM concentration. The results showed that TM is one of the appropriate data resources in the multi-spectral remote sensing to estimate the chlorophyll-a (CHL) and total suspended matter (TSM).
