摘　　要：长江上游河段存在滩多、水浅、流急的问题,航道划分多以规划为基础,规划的航道范围内存在急流、险滩、礁石斜流等不良流态,导致长江上游船舶航行的实际航迹线存在与规划航道不符的现象。基于P-分位数法提出船舶上下行航线判别方法,在不同水流条件下根据实船航行航迹带断面统计流速,动态选取P值,更加准确地对适航河段进行流速带划分,将航道进一步划分为主流带、次缓流带与缓流带,从而有效地指导船舶上下行航线的选择。该方法适用于长江上游及其他内河航道船舶航线的划分。There are many problems in the upper reaches of Yangtze River and most channels are divided on the basis of planning. The scale of the channel can not be effectively matched with the ship size and the actual channel flow conditions, leading to the existence of restricted and obstructed areas in the upper reaches of Yangtze River. Based on the P-quantile method, this paper put forward the method of determining the ship routes of upstream and downstream. According to the flow velocity statistics of the ship＇s cruise track with different flow conditions, the P value was selected dynamically. The channel was further divided into the mainstream zone, sub-slow flow zone and slow flow zone, which could effectively guide the ship routes of upstream and downstream. This method was applicable to divide the ship route in the upper reaches of Yangtze River and other inland waterways.
