At present, this method has been used in a relatively wide range of applications in the inversion of a conventional water colour factor concentration in the case II water body： applications such as chlorophyll, suspended sediment, yellow substance. On the basis of extensive field testing data of water quality, correspondingly apparent optical properties, and the full use of the existing parametric model of colour factor inherent optical properties （with the parametrization of petroleum substance inherent optical properties established in the project） the remote recognition model for oil concentration is established by introducing oil as a new water co/our factor into a biooptical remote algorithm.
