　　随着海洋测量技术的发展，海图深度基准面在实现上不统一的问题在海洋测绘实践中造成的离散性和跳变性，越来越不能满足实际应用的需求。以渤海湾为实验区进行实例分析，利用多面函数拟合的方法对点状的深度基准面模型进行连续化的处理，并对处理结果进行了分析。

With the development of hydrographic survey,the discreteness and jumping of the chart depth datum can not meet the needs of practical applications. In this paper,the lowest astronomical tide of the Bohai Bay area is selected and fitted by polyhedral function method. Furthermore,the accuracy of the fitting results is analyzed. Finally,the lowest astronomical tide model of the Bohai Bay area is built.
