摘要

In this paper, the spectral characteristics of Fuxian and Xingyun Lakes water are studied by analyzing the field spectra measurements. The observed of Chlorophyll-a (Chl-a) concentration, Suspended Sediment(SS) concentration and MODIS band combination were compared. The results show that the ratio of band 2 to band 1(r2/r1) with 250 m resolution is suitable to retrieve Chl-a concentration, while the proportion of sum-difference band 4 to band 3(r4-r3)/(r4+r3) with 500 m resolution is related closely to SS concentration.
