| 摘 要： | 文中以Gordon生物光学模型为基础,利用2004年10月实测的太湖水体固有光学特征、表观光学特征和水体组份浓度数据,构建了参数化的分析模型.基于分析模型,在400 ～ 700 nm可见光光谱的范围内,分别对无机悬浮物、有机悬浮物、叶绿素和黄色物质的光谱敏感程度进行了定量分析,重新认识了水色光谱的形成机理.最后,对进一步利用分析模型构建反演模型的关键问题进行了总结.

| Abstract: | Based on Gordon＇ s Bio-optical model,an analytical model for water color remote sensing is parameterized using field data of inherent optical properties,apparent optical properties and water quality parameters surveyed in Oct.,2004 in Lake Taihu.The sensitivity of the water reflectance to the water color parameters is analyzed based on analytical model in the spectrum range of 400 ～700 nm,and the mechanism of the water color spectrum is re-studied.Some key problems of water color remote sensing based on analytical model are summaried. |
