根据1979－1992年不同类型淤泥质潮滩涨潮前锋水沙观测资料，结合潮锋作用沿滩面上溯的强度变化进行分析。结果表明，涨潮前锋存在水流加速过程是潮锋作用的本质，其出现前提是滩面的宽展平缓，而潮位变化速率过程则决定了潮锋作用强度及其时空变化。潮锋带水体的高含沙量现象及其沿程变化在潮滩滩面发育中具有重要意义。
Based on the data of water and sediment movement at different tidal flat tidal flats during 1979-1992, the change of strength along the tidal flank was analyzed. The results show that the process of accelerating the flow of the rising tide front is the essence of the tidal front. The appearance of the tidal flats is that the width of the beach surface is gentle, while the changing process of the tide level determines the intensity of the tidal front and its temporal and spatial variation. The high sediment concentration in the tidal flats and its variation along the course of the tidal flat are of great significance.
