长江陆溪口水航道整治的必要性

陆溪口水道是长江中游的重点浅水道之一,由于汊道的兴衰交替,航槽也相应变迁,另外由于直港进口、中港汊道中部及出口处碍航浅滩的存在,导致航道维护困难,近期枯季维护水深仅为3.2m,大型油驳船队须减载运行.对陆溪口水道进行整治,是稳定航槽、改善航行条件、建设长江水运主通道的需要.

内河的整治工程资金需求量大，而且内河航道还具有准公用品和跨地区的特点，这些都造成了内河航道建设的投资吸引力不足，内河航道建设严重滞后，不能满足内河运输和国民经济发展的要求.本文运用非合作博弈的模型对内河整治工程建设资金的筹措进行研究，并结合苏南运河建设资金的筹措进行了实证分析.结果表明，本文的资金分摊模型为内河航道建设的合理筹资和利益分配提供了一个可行的方案.     

水流速度对内河船舶营运能效影响分析

本文在能源消耗和环境污染的危机下,致力于内河船舶能源消耗和温室气体排放的研究,分析了水流速度对内河船舶营运能效的影响。本分析是基于一艘客船的数据进行的,分别对不同航段下水流速度,主机转速,燃油消耗进行测量,并计算得到内河船舶营运能效。根据测量结果提出内河船舶营运能效提升策略,为内河航运业的节能减排提供帮助。     

内河集装箱班轮优先过闸管理模式探讨

文章结合2013年最新出台的《广西壮族自治区船闸管理办法》,以及近期国家关于行政审批制度改革的相关精神和要求,对集装箱班轮优先过闸条款进行探索和研究,分析了集装箱班轮优先过闸面临的主要问题,提出了一套新的市场管理模式,即主要采取企业公开"承诺制",加上"定期、定港、定线、不定船"的管理模式,通过实施"宽进严管",以期在简政放权的同时,能够充分发挥市场作用,促进企业自律,推动内河集装箱班轮运输市场的健康发展。     

嘉兴内河航运“船联网”建设的探索与实践

嘉兴内河作为浙北航区的重要组成之一,提高航运信息化程度,是当前的重要任务之一。本文在嘉兴航区现有信息化程度的基础上,结合实际,提出嘉兴航区"船联网"建设的设计原则、发展方向和总体构想,同时就船舶-桥、船舶-码头、船舶-通航环境信息感知系统构架进行分析,提出实现目标。     

Forecasting the impacts of climate change on inland waterways

Inland waterways are vulnerable to climate change as river navigation depends on water levels. Droughts can severely disrupt inland navigation services by reducing water levels either to completely non-navigable ones or to levels that oblige operators to reduce vessel load. We analyse the impacts of droughts induced by climate change using projections of river discharge data provided by eleven different climate model runs. We consider location specific characteristics by focusing the analysis on four specific locations of the Rhine and the Danube where a substantial part of the total freight activity in the European Union (EU) takes place. For the majority of the cases and scenarios considered, a decrease of the number of low water level days is projected, leading to fewer drought related disruptions in the operation of the inland waterway transport system. Although the uncertainties from the climate projections should not be neglected, the navigation sector could benefit from global warming which means that European inland waterways might be one of the few sectors where climate change can have negligible, or even positive, impact. The average economic benefit, for the cases considered, from the decrease of low water levels by the end of the century is projected to be almost €8million annually.     

内河航路改革应统筹兼顾的几个问题

本文概要地总结分析了长江内河10多年航路改革工作的状况,在此基础上提出了对未来深入改革的建议:未来内河航路深入改革和通航管理要统筹兼顾航道整治的进程,兼顾节约资源提高效益,兼顾适合于内河运输的各种船型的发展,兼顾航行船舶水上操纵的实际困难。     

内河船舶避碰路径优化研究

Analysis of the operational energy efficiency for inland river ships

This paper looks at the energy consumption and green house gas emissions of inland river shipping, and compares them with the performance of seagoing ships. The analysis is based on a case study of container shipping on the Yangtze River, China. Data were collected under both calm water and real navigation conditions, and energy efficiency operation indices under these conditions are calculated and analyzed. We find that the navigation environment can influence significantly the operational energy efficiency of inland river ships.
