Abstract

Remote sensing technology can be used to timely monitor the distribution and growth status of algae on a large scale, but the suspended matter in water bodies may affect the spectral characters of algae, resulting in an inaccuracy of the interpretation of related remote sensing images. It is very important to improve remote sensing reverse precision and to understand the influence of suspended matter in water to algae spectrum's characteristic. In this paper, the spectral reflectance of algae in water with different suspended matter concentration was measured using a Spectroradiometer with spectral range of 350-1050 nm and resolution of 3 nm. The results showed that the spectral reflectivity of the algae increased with increasing concentration of suspended matter at the band of 400-900 nm, and a clear linear relationship between spectral reflectance and suspended matter were found at the wavelength bands. The results obtained in this study could be used to analyze the effects of suspended matter in water body on the spectral reflectivity of algae, and provide a helpful way to rapidly and accurately monitor the distribution and dynamics of algae on a large scale using remote sensing.
