摘要
航道是内河航运中最关键的基础性要素,航道等级的合理划分是航运可持续发展的重要保证.进行了长江与世界内河航运发达水系航道技术等级的比较;就《内河通航标准》(GB 50139-2004)执行过程中长江航运发展存在的问题进行了系统分析,认为长江水系航道存在着航道等级划分不合理、通航标准低、航道网络化程度低及高等级航道占比低等问题;分析提出了长江航运可持续发展的几点建议:一是着手进行现行内河航运标准的修编;二是研究确定合理的长江水系航道分级层次,提高最低通航标准;三是加快高等级航道网建设,促进长江水系航道的网络化.
Channel is the most critical basic element of inland navigation,and reasonable division of channel grade is the guarantee for sustainable development of navigation.After comparing the channel grade of the Changjiang and world′s developed rivers,we analyse the problems of the Changjiang River navigation in the implementation process of Navigation Standard of Inland Waterway systematically.It is found that the Changjiang River channel has some problems of： unreasonable channel classification,low navigation standard,low level of channel network,low proportion of high-grade channel,etc.At last,we make the following recommendations for the sustainable development of the Changjiang River navigation： the first is to proceed with the revision of the existing inland navigation standards;the second is to determine a reasonable classification level of the Changjiang River′s waterway and raise the minimum navigation standards;and the third is to speed up the construction of a high-grade channel network and promote the network level of the Changjiang River.
