Chlorophyll concentration in water is an important parameter in waters study. But conventional methods are time-consuming and strenuous. In this paper

the reflectances which chaiacterized the nature of chlorophyll concentration in 400-1100 nm band in spectrum were ased to regress with chlorophyll concentrations which were measured in Reservoir Miyun. According to multi-linear regression equation

the chlorophyll concentrations estimated with correlation coefficient more than 0.94. The similar results were obtained by using step regression analysis. The different methods for estimating chlorophyll concentration were compared and possibility of monitoring chlorophyll concentration in water using reflectance data in Landsat MSS

TM

and Nimbus CZCS bands was discussed.
