This mode goes from low to high with the heighten of filling up and enlargement of sandbank (or tidal flat). 3.

这种自然演替模式随着滩涂（或沙洲）淤积增高和面积的扩涨，即按高程从低到高的顺序进行。

So the stability study of the Dongsha sandbank is very helpful to the analysis of the stability of the whole radial submarine sand ridges system and the neighboring tidal flat.

东沙是江苏岸外辐射沙脊群中的第二大沙洲，具有独特的地形地貌和水动力条件，对它进行稳定性研究为揭示整个辐射沙洲及其邻近岸滩的动态演变都非常有益。
