摘要：

Chlorophyll fluorescence properties are effective in detecting chlorophyll a concentration in lake water, which provided new optional sensitive bands to retrieval chl-a concentration in complex water. Hyper Spectral Imager (HSI) on HJ-1A satellite with great spectral resolution can be used to detect spectral characteristics of chlorophyll fluorescence peak. The effects of empirical algorithms of lake Taihu and the algorithm based on height of fluorescence peak are analyzed by using MODIS data and HSI data respectively. The results show that compared with empirical MODIS algorithms of lake Taihu, chl-a retrieval based on HSI is more similar to the in-situ reference data.
