The invention discloses a marine environment information three-dimensional visualization method, belonging to the field of a three-dimensional visualization technology. The method comprises the following steps: step 1, establishment of a three-dimensional earth model; step 2, three-dimensional visualization realization of marine environment information data, wherein the step 1 comprises three steps of data preprocessing, data hierarchy partitioning and three-dimensional earth model generation; and the step 2 comprises three steps of marine environment information data preprocessing, drawing of three-dimensional images and displaying of the three-dimensional images. By utilizing the visualization technology, the three-dimensional visualization of the marine environment information is realized, the three-dimensional earth model is constructed, and a micro background field is provided for the vivid and visual expression of the marine environment information; and by combining the characteristics of the marine environment information and aiming at marine environment factors of different types, different three-dimensional visualization methods are designed, thus the marine environment information is expressed more vividly and realistically, working personnel can analyze more visually, and the marine environment information can be utilized better.
