在实验室单一成分叶绿素水体与巢湖复杂水体的条件下,比较了基于反射率光谱与基于偏振度光谱所建模型精度上的区别。结果显示,对于复杂水质条件水体,在叶绿素蓝绿光特征波段处,偏振度光谱比反射率光谱具有更好地克服其他光学活性物质影响和保留叶绿素浓度信息的能力;而在红光特征波段处,两种光谱反演效果的差异性则较小。 Under the condition of single component chlorophyll water in laboratory and complex water body in Chaohu Lake, the difference between model based on reflectance spectrum and polarization degree spectrum was compared. The results show that for complex water quality conditions, the polarization spectrum has the better ability to overcome the influence of other optically active substances and retain the chlorophyll concentration information than the reflectance spectrum in the chlorophyll blue-green light characteristic band. At the red characteristic band , The difference between the two spectral inversion effects is smaller.
