Considering the influence of ship type, ship length and speed on ship domain, this paper established a dynamic domain model in restricted waters based on Automatic Identification System(AIS) data. Firstly, the distance and relative orientation between the target ship and own ship at each moment were calculated to obtain the single ship position's distribution diagram, then the target ship and own ship were classified based on the ship type, ship length and speed, thus to obtain the position distribution diagram of specific type of ships by combining position distribution diagram of the same type of ships. Then the boundary of ship's domain could be determined by mathematical statistics. finally, the dynamic domain model of restricted waters can be established. Taking the zhoushan luotou water area as an example, 19 different types of ship dynamic domain models are excavated. The results show that when both the type of own ship and target ship are cargo ship, the length of domain is the smallest, and when both the own ship and target ship are oil ship, the length of domain is the largest. The size of ship domain increases with the increases of ship length and speed, and the magnitude of the increase in the long axis is greater than those in the short axis. The ratio of ship domain length to ship length is not fixed, but decreases with the increase of ship length and speed, the greater the speed of the ship, the greater the decline of the ratio.
