中文摘要：

基于HYDROLIGHT光学模拟软件模拟水表面以下辐照度比R（0^-）和参数厂值，着重分析多次散射作用对f值的贡献率以及太阳天顶角、风速和bb／（a＋bb）对贡献率的影响，结果表明：多次散射作用对参数f的贡献率受到太阳天顶角、风速和bb／（a＋bb）的共同影响，使得多次散射作用具有一定的时空差异；贡献率Pms在太阳天顶角从0（°）～85（°）的范围内，随太阳天顶角的增加呈现波动状态，但这种波动随bb／（a＋bb）值的增加而减弱，Pms在0m／s到4m／s的范围内存在较大的波动，而当风速增加到4m／s时，几乎不随风速的变化而变化；多次散射作用对参数f的贡献率最大值可以达到24．41％，因此在内陆湖泊高散射特性水体中必须考虑多次散射作用对R（0^-）的影响。

英文摘要：

Based on the simulated data of R（0^-） and g simulated by the optical simulation software HYDROLIGHT, the contribution ratio influenced by the wind speeds, solar zenith angle and bb/（a＋bb） were analyzed. The result indicates that： the contribution of the multiple scattering process to the value of g is affected by the wind speeds, solar zenith angle, and bb/（a＋bb） together, so that the multiple scattering process have the spatial and temporal dif{erence; the Pms present fluctuate state with the increase of the solar zenith angle in the range of 0°to 85°, but this fluctuation decreases with the increase of bb/（a＋bb） value. Pms have largest fluctuation in the wind speeds range of 0m/s to 4m/s, but have no change with the wind speeds when the wind speeds are bigger than 4m/s; the maximum of contribution of multiple scattering process to the g value can reach to 24.41%, so the influence of multiple scattering process to the R（0^- ） in the inland lake water must be considered.
