description The invention belongs to the technical field of marine navigation, and particularly relates to a marine accident early warning navigation method based on an electronic chart. The method comprises thesteps of acquiring electronic chart information from a current position of a current ship to a preset target port sea area, and displaying a current ship route and current navigation information on the electronic chart; acquiring historical marine accident information of a sea area in a preset range of the current route; judging whether the current ship route passes through the historical marine accident area; if the current ship route passes through the historical marine accident area, displaying a first part of the ship route in the historical marine accident area by using a first warning color, and displaying in the electronic chart; and judging whether a distance between the current position of the current ship and the first part of the ship route is smaller than a first threshold value, if so, carrying out fi
