| 航道技术等级评定是航道管理重要的基础工作,它的合理划分是水运可持续发展的重要保证。首先介绍了我国第一次航道定级的情况和目前我国航道等级的现状,然后将航道定级方面的理论研究、现场调研与专家咨询的内容相结合,通过统计分析法和对比分析法,指出了我国现行航道技术等级存在的若干问题。分析结果表明,原有航道的技术等级已不能适应新时期航运发展的需要,并从航运健康持续发展和经济社会发展两个方面,论证了我国航道重新定级的必要性。最后,针对新一轮全国航道定级工作,从建议管理部门厘清航道技术等级和航道规划等级的关系、实施新的航道定级方法和重点评定范围以及合理确定航道等级划分水平年等4个方面,提出了相关建议,以供相关部门参考借鉴。 |

| Abstract: |
| Evaluating the waterway technical grade is one of the important foundational work of the waterway management， and reasonable division of the waterway grade is the guarantee for the sustainable development of waterway transport. First， this paper sets forth the status of the first waterway grading and the present situation of navigation channel classification in our country. Then， on the basis of theoretical research of the navigation channel classification， combining field investigation with expert consultation， it is found that there have some problems in technical grade evaluating of the waterways through statistical analysis and comparative analysis. Analysis results show that the original waterway grading is unable to meet the development requirements in the new period. The necessity of the waterway grade reevaluating， considering the shipping development in a healthy and sustained way and the new situation of the economic and social development, has been analyzed in this paper. At last， suggestions in four aspects for a new round of waterway grading work are put forward: navigation management departments should make clear the difference between the technical grading and planning level， implement a new waterway grading method， define the grading range， and reasonably determine the level year for the waterway technical grading， which can be valuable references in reevaluating the waterway technical grades. |
| Key words: waterway technical grade grade structure sustainable development reevaluating grade |
