| 摘 要： | 河口涨潮槽是河口的重要地貌单元。对河口涨潮槽的发育过程与演化规律的研究在理论上可以丰富河口动力地貌的内容，而在实践上对港口和通航等具有重要的意义。文章认为河口涨潮槽不仅指河口涨潮流作用下形成的冲刷槽，还包括涨潮冲刷坑、涨潮冲刷槽和涨湖水道。国内外关于河口涨潮槽研究较为薄弱，研究内容多集中于涨潮槽的几何形态、涨落槽优势流判别和悬沙输移等方面，定性研究较多，缺乏全面而系统的定量研究，尤其缺乏成因机制方面的深入研究和沉积环境的研究。长江口涨潮槽种类较多，具有一定的研究基础，对其进行系统全面的研究具有重要的意义。

| Abstract: | :Flood channel is one of the important geomorphologic units. The study of evolution and regulation of flood channels in estuaries will enrich the contents of estuarine dynamic geomorphology in theory and guide the construction of port and navigation channel and so on in practice. Flood channels should include the flood holes, flood channels and flood courses according to the current studies. In fact the research works about flood channels in estuaries from national to international literatures are still rare. The study contents center on geometry of flood channels, determination of dominated-tidal flow, suspended characteristics. In the near future, comprehensive, systematic and quantitative studies, especially the aspects of formative mechanism and sedimentary environment should be enhanced due to the lack of the studies in these aspects. Flood channel in Changjiang Estuary are worth to be paid more attention to in terms of their amounts and different types. |
