摘　　要：介绍了SeaWiFS资料的基本处理方法和海水叶绿素浓度提取方法,针对目前SeaWiFS资料沿岸二类水域的数据失效问题,提出了解决方法。并以珠江口为例,将经改进算法处理后的SeaWiFS数据用于叶绿素信息提取,经与实测数据对比,平均误差为29.6％。The models of retrieving chlorophyll (Chl) concentrations, together with the basic process of SeaWiFS imagery, are introduced. A simple solution was proposed to retrieve SeaWiF invalid data in highly turbid waters in Pearl River estuary (case 2 waters). Finally, chlorophyll (Chl) concentrations in Pearl River estuary are extracted by using corrected SeaWiFS data. The results show the mean standard error is 29.6% between the retrieved values and in situ data.
