Variation of Spectrum of Photosynthesis Available Radiation Absorbed by Underwater Optical Medium with Depth in Lake Taihu in Summer
夏季太湖光学介质获取的光合有效辐射能量谱随深度变化规律的研究

Normalized spectrum of photosynthesis available radiation(PAR),which was absorbed by all kinds of medium per unit volume of water at different depths,was calculated by the data from downward and upward irradiance and absorption coefficients of phytoplankton,non-algae particles and chromophoric dissolved organic matter(CDOM) in 41 locations in Lake Taihu from July 29 to August 1,2006.The results showed that there were two peaks at about 450 nm and 675 nm in the normalized spectrum of PAR absorbed by phytopla...
