| 摘要: |
| 以2008年10月太湖实测数据为基础,用改进的指数函数和线性法拟合非色素颗粒物吸收和浮游植物色素吸收,根据二者的加和关系,建立总悬浮颗粒物吸收分解模型,依据参量的不同,分别构建了两个分解模型(Mod-4和Mod-5),两者都可以较好的分解出太湖水体浮游植物色素吸收和非色素颗粒物吸收,但Mod-5的拟合精度稍高于Mod-4.研究结果对于进一步探索和建立太湖区域生物光学模型,精确反演水质参数具有一定意义. |

| Abstract: |
| Based on the data measured in site in Iake Taihu in October 2008,two models, namely, Modes with five unknown pa-rameters and Mod-5 with two unknown parameters, were developed to decompose the absorption due to suspend particulate matter (SPM ) into absorptions due to phytoplankton pigment and non-pigment particulate absorption. The result showed that both of the models were good for the accurate decomposition. But Mod-5 was better than Modes and Mod-5 can be preferentially recommended,which was helpful to develop an appropriable and applicable bio-optical model for retrieval of water quality parameter in Lake Taihu. |
