摘  要:长江中游航道货运承载能力是航运发展规划的数据基础。将长江中游不同尺寸的航段相连组成多级航道,以任意起运港和终点港之间货流量为变量,货流量之和最大为目标函数,以货运网络OD矩阵和各航段通过能力等为限制条件,用目标函数的最大值来表征长江中游航道货运承载能力。运用复杂网络理论和方法,结合港口吞吐量数据,推算货运网络OD矩阵;运用船舶跟驰理论,结合船舶领域参数,计算各航段通过能力。研究结果表明,长江中游航道货运承载能力为68.8亿t,其中长江中游下行航道货运承载能力36.9亿t,限制航段为岳阳往武汉航段,长江中游上行航道货运承载能力21.9亿t,限制航段为黄石往九江航段。Carrying capacity is the basic date of shipping developing planning of Yangtze River middle waterway. The multistage waterway was connected by different sizes segment in the middle reach of Yangtze River. To study carrying capacity, the network model with cargo OD structure was estab lished, in which the cargo flows between arbitrary original port and destination port is the variables, and the sum of all goods flows is the objective function,to get the cargo network OD matrix and seg ment transit capacity. Results show that the carrying capacity of Yangtze River middle waterway is 6.68 billion tons per year, which down going channel is 3. 69 billion tons per year with the limited segment is from Jingzhou to Wuhan, and up going channel is 2.19 billion tons per year with the limit ed segment is from Huangshi to Jiujiang.
