卫星海洋遥感反演海中叶绿素浓度,对海洋初级生产力估算及赤潮预报均有重要意义.本文介绍了SeaWiFS卫星传感器业务化算法OC4,利用SeaDAS软件反演中国东海叶绿素浓度,并与东海同步现场数据进行验证.结果表明:利用SeaDAS方法计算的东海叶绿素含量与实测含量之间具有较好的相关性,但总体上计算值要高于实际测量值;东海叶绿素含量具有分带性,河口、近岸海域高,中陆架次之,外陆架最低,这种发育特点与该海域的陆源营养盐输入、海洋动力系统有着显著的关系.

Retrieval of chlorophyll concentrations by Ocean Color Remote Sensing is of great significance to the estimation of ocean primary production and red tide forecast. The method of SeaDAS-OC4 to calculate chlorophyll concentration based on SeaWiFS data was introduced in this paper. After that, SeaDAS method was used to retrieve chlorophyll concentrations in the East China Seas. The results show: 1)The calculating chlorophyll concentration has some good linear correlation with measurement chlorophyll concentration in situ despite the former one general being greater than the later. 2)Distribution of chlorophyll concentration in the East China Seas is characterized with high concentration in estuarine and inner shelf, medium in middle shelf and low in the outer shelf. It is most likely controlled by nutriment input and marine dynamic systems in that area.
