【 摘 要 】

In order to obtain the ship domain in narrow fairways, Combined with the automatic identification system of ships, it contains a huge amount of data and wealth of ship information. This paper deals with AIS data from zhou shan luotou water channel by using SQL 2012 database, We establish dynamic and static information database of narrow channel. Selecting target ship and calculating the distance and relative azimuth of other ship to the target ship at each moment, obtaining the single ship's position distribution map, classifying the speed of ship, superimposing the single ship's position distribution map at same range of speed, get the specific types of position distribution map, the boundary of ship domain is determined by mathematical statistics, We study the ship speed in the interval of 6 ∼ 8,8 ∼ 10,10 ∼ 12,12 ∼ 14,14 ∼ 16 knots at these five classes of ship domains, through analyzing, the length at the long axis and short axis are increasing with the speed of ship, the increase magnitude at the long axis is greater than short axis.
