针对太湖水域特有藻种组成的浮游植物光谱吸收系数,利用实测数据对Ciotti光谱吸收系数模型进行改进和演化,得到新的基于藻类粒径组成(模型3)和种类组成(模型4)的太湖水体浮游植物光谱吸收系数模型。对模型进行比较发现,模型3和模型4能够较好地模拟太湖水体浮游植物的光谱吸收系数,分别适用于中、低和高叶绿素质量浓度的太湖水体浮游植物的光谱吸收系数的拟合。
Considering the spectral Absorption coefficient of the special algal species in the Taihu Lake,Ciotti model is improved to derive the new models i.e.Model 3 and Model 4 by means of the observed data.The algal size is involved in Model 3 and the algal composition in Model 4.It is learnt from the comparison between the 2 models that either Model 3 or Model 4 can better fit the spectral Absorption coefficient for the phytoplanktons in the Taihu Lake.Model 3 is more suitable for the conditions of the lower or medium chlorophyll-a concenrations,and Model 4 for the conditions of the higher chlorophyll-a concontrations in the Taihu Lake.
