摘要

Abstract

The optical properties of a waterbody are subjects of research on limnological hydrooptics. The optical properties of

and parameterization methods for

three impurities in Taihu Lake

namely unpigmented suspensions

yellow substance and phytoplankton algae

are analyzed in detail in this paper dealing with the optical types of Taihu Lake waters both in winter and in summer. The results showed that: 1) The optical parameters of suspended particles can be calculated by the application of Mie Theory; 2) The absorption of yellow substance decreases exponentially with increasing wavelength

with the mean value of decreasing rate being about 0.014 nm−1; 3) Taihu Lake waters appeared to be of type PY in winter

with suspended particles and yellow substance being the dominant light absorbers

and type CPY in summer

with suspended particles

yellow substance and phytoplankton algae being the dominant light absorbers; 4) In winter or summer

unpigmented suspension has the main effect on the scattering property of Taihu Lake waters.
