运用多时相卫片中潮间浅滩出露经验频率与实际潮位累积频率的联系,可以从短期多时相卫片直接编绘特征潮位线分布图。在理想抽样方案下,编绘可以在无任何实测潮位记录条件下进行。在不合理抽样条件下,通过若干控制潮位站的潮滩出露经验频率与实测潮位累积频率的关系曲线,也可以进行近似的编绘。文中给出杭州湾南岸潮间浅滩的应用实例和关于误差的讨论。
Based on the correlation between the experience frequency of intertidal shoal and the cumulative frequency of actual tide level in multi-temporal synoptic patches, the distribution maps of characteristic tidal level can be directly mapped from the short-term multi-temporal synoptic patches. Under the ideal sampling plan, compilation can be carried out without any recorded tidal record conditions. Under the condition of unreasonable sampling, the approximate plotting can also be done through the relation curves between the empirical frequency of tidal flat and the cumulative frequency of measured tide by controlling a number of tide stations. The paper gives an example of the application of intertidal shoals on the south bank of Hangzhou Bay and a discussion about errors.
