Study on characteristic of the absorption and scattering coefficients of Taihu Lake waters

The optical property of water body is the foundation of research on limnological hydrooptics.In this paper,the absorption and scattering coefficients of Taihu Lake waters both in winter and summer are calculated by using the parameterized model of the hydrooptical property.Moreover, the classification of the optical types of the waters is also carried out.The resups show that Taihu Lake in winter appears to be of water type PY with suspended particles and yellow substence being the dominant light absorbers,and in summer of water type CPY,with suspended particles, yellow substance and phytoplankton algae being the dominant light absorbers.Upon this,whether in winter or in summer,unpigmented suspension has the main effect on the scattering property of Taihu Lake waters.
