中文摘要：
水体的固有光学特性是描述水体辐射传输的基本光学特性,是建立水质参数遥感模型的基础.黄色物质、非色素悬浮物和浮游植物是影响内陆水体光学特性的3种主要物质,对巢湖水体中这3种物质在波长为400-800 nm的吸收系数进行了测量和分析.结果表明,各组分的吸收系数随其含量的增加而增加;黄色物质和非色素悬浮物的吸收系数随波长的增加呈负指数形式递减;浮游植物吸收光谱的形状与不同藻类的色素组成密切相关.绿色到近红外波段范围是遥感监测内陆水质参数的最佳波段.
英文摘要：
The inherent optical properties are the fundamental optical properties describing the radiation transmission in water body, which are mainly influenced by CDOM, tripton and phytoplankton. The absorption coefficients of the above three factors in Chao Lake within the range of 400 - 800 nm were measured and analyzed. The results showed that the values of the absorption coefficients were in direct proportion to the contents of the principal optical water quality parameters. The absorption coefficients of CDOM and tripton decreased with increasing wavelength exponentially. The shape of phytoplankton absorption spectra was decided by the pigment components and the algae species. The green to nearby infrared spectral area was the best area to extract optical water quality parameters from remote sensing data.
