本文具体讨论了上海淤泥质潮滩的潮锋作用过程，定性给出了潮锋的形成机制，认为潮锋作用及其水体高含沙量现象的本质在于“潮锋带水体水流加速效应”，即，由于潮滩坡面变化平缓的特殊性，涨潮水体前锋沿程存在着一持续时间可达数十分钟的水流加速过程。最后，本文初步探讨了潮锋作用在滩面塑造过程中的地位，并重新定义了潮锋作用的内容。
This paper discusses in detail the tidal front process of the muddy tidal flat in Shanghai and gives the mechanism of the tidal front qualitatively. It is believed that the essence of the tidal flanks and the high sediment concentration of the water body lies in the “water flow acceleration effect of the tidal flank” That is, due to the particularity of the gentle changes of the tidal flat, there is a water acceleration process lasting for tens of minutes along the rising front of the rising tide water body. Finally, this paper discusses the role of the Chao Feng front in shaping the beach surface and redefines the role of the Chao Feng front.
