摘要：

There is a little trouble to retrieve chlorophyll-a concentration ( Chl-a) through remotely-sensed imageries in turbid waters, which contains many suspended sediments largely affecting the signature of water-leaving radiance due to phytoplankton pigment. Based on the in situ measurements during the period of 2004 2010, the two-band, three-band, enhanced three-band and four-band models were, respectively, regionally parameterized for the application in Tai Lake. Then the four parameterized models were validated by the in situ data in Chao Lake, almost the same water environment as in Tai Lake. The strongest linear relationship between Chl-a and the four-band model (R(2) varying in the range of 0.57 and 0. 95, RMSE in the range of 2.39 and 6. 74 mu g/L) shows that the four-band model is the best for both the Tai Lake and the Chao Lake.
