摘要:

后向散射系数是水体重要的固有光学量之一,是水色反演半分析模型的重要输入参数,与水体组分有着密切关系。回顾了近年来国内外有关水体后向散射特性的研究进展,主要包括纯水、浮游植物和悬浮泥沙等无机颗粒物的后向散射特性,以及不同颗粒物的后向散射光谱变化性等。此外,还阐述了后向散射系数的理论基础和测量方法,并探讨了影响水体后向散射特性的影响因子,最后提出了水体后向散射的研究方向和发展前景。

关键词: 后向散射系数水色反演固有光学量水体组分    
Abstract:

The spectral backscattering coefficient is one of the important inherent optical properties,and also is an important input parameter of water color quasi-analytical inversion model.It is highly related to the concentration of water constituents in the water.This study reviews the progress in the water backscattering that includes the backscattering properties of water,various phytoplankton and other suspended inorganic particles,at the same time,this paper also discusses the backscattering spectral varition of the different particles.Otherwise,this study describes the theoretical basis and the way how to achieve the backscattering coefficient,systematicaly analyzes the variation characteristics of particulate backscattering coefficient and backscattering ratio,and finds that particle-size distribution and average particle refractive index are the main influencing factors.In order to know if the chlorophyll concentration influence the water backscattering properties,the relationship between them is discussed in the paper.Finally,the future development perspective and research fields are proposed.

Key words: Backscattering coefficient    Water inversion model    Inherent optical properties    Water constituents
