积水沉陷区水体的表观光学特性参数测量与分析

Measuring and Analysis of Water Apparent Optical properties in Water Subsidence Area

通过实际测量试验区的积水沉陷区水深值,了解水体光学特性随水深不同而引起的衰减特征变化,建立水深与光谱特性响应间的关系表达式,确定获取水深信息的最佳波谱范围;揭示了叶绿素、悬浮物质、CDOM等水体组分与水体光谱特征变化的关系,探讨因水体各主要组分变化而引起的水体光谱吸收光谱、散射光谱的变化规律。

Through the actual measurement of the water depth in water subsidence area,understand the water optical properties was that the different water depth could cause the attenuation characteristics change,establishing the expression of water depth and spectrum characteristics response,determined the best spectrum scope to get water depth information.It revealed the relationship between water components of chlorophyll,suspended material,CDOM etc.and water spectrum characteristics change,so it depicted the change rule of water absorption spectra,scattering spectra because of the main component changing.
