1 潮滩的均衡态与非均衡态淤泥质潮滩多年的平均动态,常以滩面在铅直方向的蚀淤速率(淤强)和潮滩外缘在与岸垂直方向上的进退速率(即淤长速度)来衡量.对于淤强和淤长速度均为0或接近于0的潮滩,称之为稳定潮滩.但在较短时段中(如短于一年),潮滩某些地貌单元所出现的蚀淤和进退尺度可比多年平均值大1～3个量级,甚至与潮滩平均动态的变化趋势相反.本区,
1 The average dynamic of the tidal flat in the equatorial and non-equilibrium silt tidal flat over many years, often with the erosion rate of silt surface in the vertical direction (silt density) and the vertical velocity of the tidal flat in the vertical direction ( That is, silt growth rate.) For a tidal flat with a silt density and silt growth rate of 0 or close to 0, it is called a stable tidal flat, but in a relatively short period of time (eg, less than a year) The erosion and advancing scale of some landform units may be 1 ~ 3 orders of magnitude larger than the multi-year average, even with the trend of the average dynamic of the tidal flat. In this area,
