Abstract: In recent years, the extreme weather conditions such as rainstorm and drought have resulted in extreme water level in the middle reaches of the Yangtze River and changes of the duration of water periods, and affected impact on transport efficiency, safety, and economy of the Yangtze River shipping. This paper established a comprehensive quantitative model for the impact of changes of the duration of water periods on shipping logistics cost in the middle reaches of the Yangtze River. The research results show that changes of the duration of water periods have different effects to shipping logistics cost per freight ton of different ship types. The longer the duration of flood period or dry period is, the greater the impact on shipping logistics cost per freight ton; the influence of the extension of the dry period on shipping logistics cost per freight ton is much greater than that of flood period.
