Abstract:

基于2011年5月渤海湾典型站点的CTD观测数据和实测光谱数据分析了渤海湾的水体光谱特性。通过对比实测站位水体光谱和温度、盐度、密度、光合有效辐射和叶绿素浓度在水体中的分布状况,分析了海洋环境要素对水体光谱特性的影响。结果表明在510~620 nm光谱范围内,水体光谱辐射峰的高度由叶绿素浓度和光合有效辐射共同作用决定;在380~440 nm和705~800 nm波长范围水体光谱辐射峰的高度不仅受叶绿素浓度和光合有效辐射影响,还受其他环境要素影响。
Based on the CTD data and the measured spectral data of Bohai Bay in May, 2011, the water spec-tral characteristics of typical survey stations are analyzed. In this paper, the effects of marine en-vironmental elements on the spectral properties of the water body are analyzed by comparing water spectra and the distribution of temperature, salinity, density, photosynthetic active radiation and chlorophyll concentration of Bohai Bay. The results showed that the water body spectral radiation peak height is determined by the chlorophyll concentration and photosynthetic active radiation interaction in the 510 - 620 nm spectral range, but it is determined not only by the chlo-rophyll concentration and photosynthetic active radiation interaction, but also by other environ-mental factors in the 380 - 440 nm and 705 - 800 nm spectral range.
