摘　　要：掌握内河船舶的交通流量特征是进行合理的航道和通航设施规划、设计、运营、管理与控制的前提.根据大量的航道(段)船舶交通流资料,提出了两个不均衡系数来反映内河船舶流量的时空分布特征.其中,具有一定保证率的单位流量不均衡系数能够较好地反映内河船舶流量的时间分布特征,拓展了《船闸总体设计规范》中月运量不均衡系数的内涵;单位流量方向系数则表明船舶单向流量并不一定等于双向流量的一半,研究内河船舶交通问题时,应按船舶航向分别进行讨论.The characteristics of traffic flow in inland waterways are the basis for the reasonable planning, design, operation, management, and control of navigation waterways and facilities. Based on lots of data, two nonequilibrium coefficients are introduced to reflect the temporal and spatial distribution of inland vessel traffic flow. The unit flow non-equilibrium coefficient with a guarantee percentage is reasonable to reflect the temporal stochastic characteristics, and to extend the meaning of the monthly-flow non-equilibrium coefficient in Code for Master Design of Ship locks. The unit flow direction coefficient shows that the flow in a single direction is not always half of the total flows in two directions. So the problem about inland vessel transport should be discussed according to the direction of vessel traffic flow.
