摘　　要：基于非线性随机理论和数理统计理论,提出了航道交通流分析中统计时间单位的选定方法,并以京杭运河为例,分析了其统计时间单位约为50min,结果验证了统计时间单位选定方法的正确性。Appropriate interval time is the basis of valid investigation and statistics for ship traffic. Stochastic theory and statistics theory are applied to determine the measurement interval for the ship traffic flow. The detailed shipping data at ship locks are used in the analysis. The results show that the reasonable measurement interval is about 50 minutes to satisfy the stability requirement. This study method should be extended to the study of waterway traffic problem.
