The invention provides a navigation environment visualization representation method for ship visual navigation. The method includes the following steps that: a geometric layer is constructed, wherein the geometric layer includes a geometric model of navigation environment and thematic elements, initial positions and statuses, ship dynamic data and movement navigation point position information; a physical layer is constructed, wherein the physical layer is used for representing the physical characteristics of the thematic elements in the navigation environment and laws of physics which the thematic elements should follow in the navigation environment; a temporal layer is constructed, wherein the temporal layer concludes the temporal characteristics of the navigation environment and thematic elements to states and processes and specifies a researched time domain as a continuous model based on time density; and a semantic layer is constructed, wherein the semantic layer includes topic semantic, space semantic and process semantic and reflects the physical natures of the dynamic change processes of the navigation environment elements and the influences of the navigation environment elements on ship visual navigation. With the method of the invention adopted, the navigation environment and thematic elements can be integrated under a unified time-space frame, and centralized and unified representation of navigable environment information can be realized, and the accuracy and efficiency of visual time-space analysis can be improved.
