太湖水中光辐射传输的数值模拟
杨平, 蔡启铭

摘要:
水体的初级张产力状況在很大程度上取决于水沐光学状況,与透光层深度Zeu密切联系。Zeu这类表观光学属性取决于光辐射在水中的传输状况,最终取决丁水体:本身的微 物邢汴质如吸收和散射等。本文根椐太湖悬浮质的实测资料计界所得的水体固有光学参位,利用数值模拟的方法研悬浮质浓度垂直梯变的太湖水体中光辐射的传输情況并讨论了诸因子的影响。

Numerical Model For Transferring Of Solar Radiation In Taihu Lake

Abstract:
The state of primary production in a lake is greatly affected by the optical conditions in the water, and closely related to the euphotic depth Zcu, The apparent optical parameters such as Zcu depend on the transferring of solar radiation in vvatcr, consequently, on the optical coefficients of water body such as absorptance aud scattering. In this paper, the field data of suspended materials in Taihu Lake are used for computing of inherent optical parameters of the lake. With the computed results, a numerical model is developed to study the transferring of solar radiation in the lake in which the concentration of suspended materials is considered to be variable vertically. Using this model the factors which influence on the transferring of radiation in the water are discussed.
