| 摘 要： | 江苏Jing港潮滩地处北温带，是典型的淤涨型淤泥质潮滩。通过对2001年冬季Jing港潮滩的野外观测和样品的室内处理，在分析江苏淤泥质潮滩海冰形成机理的基础上，探讨了温带潮滩上海冰的分带性；阐析海冰作用下潮滩微地貌类型——擦痕、冲刷坑和泥斑的形成机制：最后对浮冰带的稳定性、潮沟和盐沼植被对浮冰形成的影响，海冰对潮间上带淤积过程的作用和浮冰作用形成的侵蚀型微地貌在地层中保存的可能性进行了探讨。

| Abstract: | : The Jianggang tidal flat, typical deposit muddy flat of Jiangsu, locates at the northern Temperature Zone. In the winter of 2001, we investigated the Jianggang tidal flat and analyzed samples that we had collected. Based on the analysis of the formation mechanism of sea ice on the muddy tidal flats in Jiangsu, the paper probes into the zonal distribution of sea ice on Jiangsu tidal flats. Then, the forming mechanism of the three kinds of tidal flat micro-topography including scrape, scoured pit and mud speckle are discussed. The scrapes are caused by floating ice digging, the scoured pits by tidal current erosion and the mud deposits by ice melting. The stabilization of floating ice belt, the effect of creek and salt marsh vegetation on the formation of floating ice, the effect of sea ice on the deposition of supra tidal and the feasibility of conservation of erosional micro-topography caused by floating ice are discussed at the end of the paper. |
