有色可溶性有机物(CDOM)是溶解性有机物的重要组成部分,其光学行为和生物地球化学循环对水体生态系统有明显影响,是海岸带调查的重要指标。通过遥感方法监测水体CDOM的变化是海岸带环境动态监测的重要方法,介绍了CDOM遥感监测的原理及常用的遥感数据,并通过墨西哥湾西北部的密西西比—阿查法拉亚海湾水域系统进行CDOM光学性质季节性遥感调查实例,揭示了在海岸带地区,不同的季节、不同的水样深度条件下,CDOM的光学性质表现出的不同特性,其变化与盐度、溶解氧等的含量密切相关,是海岸带调查研究的重点。 Color soluble organic matter (CDOM) is an important part of dissolved organic matter. Its optical behavior and biogeochemical cycle have significant effects on water ecosystem, which is an important indicator of coastal zone investigation. Monitoring the change of water body CDOM by remote sensing is an important method of dynamic monitoring of coastal zone environment. The principle of CDOM remote sensing monitoring and the commonly used remote sensing data are introduced. CDOM optics is carried out through the Mississippi-Atchafala Bay waters system in the northwestern Gulf of Mexico A case study of seasonal remote sensing reveals the different optical properties of CDOM in the coastal zone, different seasons and different water depths. The changes of CDOM are closely related to the contents of salinity and dissolved oxygen, Is the focus of the study of coastal zones.
