摘要
黄色物质是中国近海水体光学特性的重要影响因素,是海水有机污染情况的指示因子。基于在中国近海海洋光学调查中获取的典型海区多年的黄色物质吸收系数数据,对黄色物质400 nm和440 nm吸收系数进行了分析,研究表明:(1)黄海、珠江口和南海海区黄色物质含量呈多年增加的变化趋势;(2)珠江口海区黄色物质含量最高,黄海次之,南海最低;(3)南海黄色物质含量多年增长的百分比最高,超过了50%。
The yellow substance is one of the important influence factors of ocean optical properties in China＇s nearshore area, which is also the organic pollution instructions factor of sea-water. Based on the yellow substance absorption coefficient data gained from marine optical investigation in different years, the absorption coefficient of yellow substance at 400 nm and 440 nm was analyzed. The results show that： （1） the content of the yellow substance has increased during the past years in the Yellow Sea, South China Sea and the area of Pearl River mouth; （2） the content of the yellow substance is highest in the area of Pearl River mouth, then is the Yellow Sea and the South China Sea; （3） the annual growth percentage of the yellow substance content is the highest in the South China Sea, with mare than 50%.
