Marine ecological environment damage investigation method

The invention discloses a marine ecological environment damage investigation method, which comprises the following steps: constructing a marine ecological environment damage remote sensing investigation information base according to different marine ecological environment damage types; determining an optimal remote sensing observation mode corresponding to the marine ecological environment damage event to be investigated according to the constructed marine ecological environment damage remote sensing investigation information base; acquiring remote sensing image data corresponding to the marine ecological environment damage event to be investigated according to the determined optimal remote sensing observation mode; carrying out image preprocessing on the obtained remote sensing image data; and performing marine ecological environment damage feature recognition and extraction on the preprocessed remote sensing image to generate a remote sensing survey result of a marine ecological environment damage event. According to the method, the marine ecological environment damage is investigated by utilizing an automatic screening remote sensing means, the man-made subjective uncertainty in remote sensing satellite data selection and processing method selection is avoided, and the efficiency and accuracy of marine ecological environment damage investigation are improved.
