内河航道定级与船舶大型化发展

随着我国经济的进一步发展和可持续发展战略的实施，运能大、占地面积小、能耗低、污染少的内河航运必将发挥出更大的作用。此外，内河船舶标准化、大型化的发展趋势日趋明显，小吨位船舶的运能及经济性劣势迫使其快速淘汰，不少地区早年的航道定级已然不适应内河航运的发展需求。若城市的开发建设按不合理的航道定级标准进行规划控制，将极大地限制内河航运的发展，并对船舶的航行构成重大安全隐患。结合实际情况，探讨长三角地区内河航道定级调整的若干设想，并提出相关建议。

Inland waterway classification and large-sized trend of vessels

Along with the further development of economy in China and the implementation of sustainable development strategy, the inland river shipping with advantages of high shipping capacity, low land occupancy, low energy consumption, and little pollution will certainly play greater functions. In addition, the standardization and large-sized trend of inland river vessels become more and more obvious. The small-tonnage ships are being rapidly obsolete due to its disadvantages in capacity and cost-effectiveness. The waterway classification of many districts which was defined in early years has already been not adapted to the developing need of inland river shipping. If the urban development is planned and controlled according to the inappropriate waterway classification standard, the development of inland river shipping will be greatly restricted and it will create great concerns to the navigation safety of vessels. Based on the actual situations, this paper is set out to discuss several ideas and bring forward relevant proposals for the adjustment of inland waterway classification at the Yangtze River delta region.
