应用水色卫星（ＳｅａＷｉＦＳ，１９９７年由美国发射）近海监测海水ＣＯＤ及油污染状况及其分布，在广东珠江口、大亚湾等近海海域，进行了水体波谱测试与分析，建立了与水色卫星相应波段的ＣＯＤ及油的质量浓度信息提取模型，并用此模型处理了１９９８年６月３０日过境的水色卫星图像，得到了珠江口、大亚湾近岸水域ＣＯＤ及油分布的专题图 SeaWiFS (launched by the United States in 1997) was used to monitor seawater COD and oil pollution and its distribution offshore. Spectral tests and analyzes were carried out in waters off the Pearl River estuary and Daya Bay in Guangdong Province. COD and oil mass concentration information extraction model, and used this model to deal with the transit of satellite images on June 30, 1998. Thematic maps of COD and oil distribution in the Pearl River Estuary and Daya Bay coastal waters were obtained
