摘　　要：基于长江南京以下12. 5 m深水航道船舶流数据以及沿程各水文站的潮位数据,以交通流理论为基础,结合水文分析,研究长江12. 5 m深水航道仪征、丹徒直、口岸直、福姜沙和南通水道的船舶流量、流向特征。研究结果表明:上行船舶仪征水道大船占比为73. 2%,口岸直水道大船和小船占比相当,丹徒直、福姜沙和南通水道大船占比33%左右;下行船舶各水道大船占比在31. 5%~41. 3%,小船占优势;大潮时船舶流量受潮汐影响显著,上行船舶逐时流量过程与潮位过程关系显著,下行船舶受落潮影响明显;小潮时上下行船舶与潮位过程关系不明显;一个月内日船舶数量与大潮小潮没有直接关系。研究成果可为深水航道维护和通航安全方案的制定提供参考。Based on the ship flow data of the 12.5 m deep water channel of the Yangtze River below Nanjing and the tide level data of various hydrological stations along the route,based on the theory of traffic flow,and combining with the hydrological analysis,we study the flow and flow characteristics of the 12.5 m deep water channel Yizheng,Dantuzhi,Kouanzhi,Fujiangsha,Nantong waterway.The results show that the big ships account for 73.2%in Yizheng channel’s ascending vessels,the big ships and the boats account for the same proportion in Kouanzhi channel,the big ships account for about 33%in Dantuzhi,Fujiangsha and Nantong waterwaysr.As for the descending vessels,the big ships account for 31.5%~41.3%in all the channels.The ship flow is greatly affected by tides during the spring tide,and the hourly flow of the ascending ships is positively correlated with the tide level.The descending ship is affected obviously by the ebb tide,and the relationship between the upper and lower ships and the tidal level process is unobvious during the small tide.The daily number of ships within a month is not directly related to the tides.The research results may serve as reference for the development of deep channel maintenance and navigation safety plans.
