Based on the theory of object-oriented image analysis, this paper carried out a multi-scale segmentation of SPOT5 image to obtain sea use objects at different spatial scales. By integrating objects'spectral, shape and context features to formulate detailed procedures of information extraction, areas of pond aquaculture were identified with classification accuracy better than 94%, indicating that the method of object-oriented image analysis is effective in the extraction of pond aquaculture information in coastal areas. It would promote the operational monitoring and management of sea use.
