摘　　要：为分析厦门港主航道浮标在外力作用下的漂移规律,防止由其漂移量过大引起的船舶导航误差,根据浮标遥测位置数据,计算浮标在漂移过程中通过某一位置点的频率,建立浮标漂移位置的概率密度模型,得到厦门港主航道浮标漂移位置的概率密度分布。在此基础上分析浮标漂移位置热点区域和漂移规律。实际应用结果表明,所建立的浮标漂移位置概率密度模型可以为浮标的漂移分析提供一种新的理论方法,从而为浮标的位置维护提供有益的参考。In order to analyze the drifting rule of buoys in Xiamen Port main channel under external force,and to prevent the ship navigation error caused by excessive deviation,according to the telemetry position data of buoys,the frequency of buoys passing through a position point in the drifting process is calculated,the probability density model of buoy drifting position is established,and the probability density distribution of Buoy drifting position in Xiamen Port main channel is obtained.On this basis,the hotspot area and the drifting rule of buoys are analyzed.The practical application results show that,the probability density model of buoy drifting position can provide a new theoretical method for the deviation analysis of buoys,thus providing useful reference for position maintenance of buoys.
