摘要
中国近海是典型的二类水体,水色三要素组成复杂,水色三要素是影响中国近海水体光学特性的重要因素。基于2006-2007年在中国近海进行的现场调查,获取了1 012个站位的三要素吸收系数数据,对三要素吸收系数的比例分布特征进行了分析。结果表明:在近岸海区二类水体区域,非色素颗粒占主导,在渤海海区所占比例高达57%;在远洋海区,浮游植物和CDOM占主导,两者共同决定了远洋水体的光学性质,叶绿素和CDOM所占比例高达90%以上;中国近海三要素吸收系数的比例分布,占主导作用的是黄色物质和非色素颗粒物,所占比例分别为36%和34%;浮游植物色素所占比例为27%。
The optical properties of the coastal waters of China are classified as Class II waters with complex three elements of water color, an important factor which affects the optical properties of China＇s coastal waters. In this paper, based on the 1012 data of three elements absorption coefficients from the offshore survey in 2006 and 2007, analysis is conducted on the proportion distribution characteristics of three elements absorption. The results show that in coastal Class II waters, de-pigmented particles are the leading factor, which reaches a proportion of 57% in the Bohai Sea; in open seas, phytoplankton and CDOM are dominant, which determine the optical properties of ocean waters, with the proportion of chlorophyll and CDOM higher than 90%. In China＇s coastal waters, colored dissolved organic matters and de-pigmented particles are the dominant factors, with a proportion of 36% and 34%, respectively. In contrast, phytoplankton pigments account for 27% in total.
