摘　　要：本文介绍了黄海海底辐射沙洲与潮汐通道的可视模型以及建模的方法。根据该海区３年的测量数据（或海图数字化数据），通过分形内插，生成连续多年时／空水深数据序列。然后建立一组反映海底地形及其变化的数学模型。在此基础上，通过可视化处理。Visual models and its forming methods of submarine radiative sandbar and tide channal in the Yellow Sea have been introduced in this paper. According to the depth data surveyed for three years separately (or digitizing data of chart) in the area, we have generated a spatial-temporal depth data sequence of continuous multiyear through fractional interpolation. Then a group of mathematical models for submarine topography change are established. Based on this, by the visualizing treatment, manifold visual models of submarine topography and its change have been formed in the area beginning from 1968 to 2000 year.
