摘要
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。
Tidal flat maps with special tide level isolines could be compiled directly by LANDSAT images in a short time series, based on the relation between tidal flat exposure frequency in LANDSAT samples and accumulation curves of local tide level. The works in the southern bank of Hangzhou Bay and the discussion on accuracy have been introduced.
