Effect of Inherent Optical Parameters on Average Penetration Depth of Photon Flux and the Integral Average Cosine of Underwater Light Field in Lake Taihu During Summer
夏季太湖水体固有光学参数对光传输行程、积分平均余弦影响的研究

Based on the inherent optical parameters of the water and water quality data in lake Taihu from 2006-07-29 to 2006-08-01, the effect of scattering on the penetration path along the original direction of the flux and the Integral average cosine of underwater light field were study by the radiative transfer theory, and the possible mechanism was analyzed. There were increasing trend from northwest to southeast of them. There were a nonlinear relation between them and concentration of Chl-a, suspended matter, inorganism matter, organism matter. The relation was described by logarithmic function. The study was helpful for bio-optical model and the environmental effects of photosynthetic active radiation in waters.
