摘　　要：水深是表达海洋深度变化的基础数据,实时水深是舰船航行和海岸带军事行动的重要影响因子。本文从实用角度出发,采用海图水深作为静态水深,基于余水位订正的预报水位作为动态水位,提出了一种顾及实时水深区域变化特征的实时水深模型。实验表明,该模型实现了实时水深的快速求取,一定程度上可以满足航海和军事应用需求。Sounding is the basic data of presenting sea. depth. The instantaneous sounding is one important influencing factor of navigation and milita：ry activities. But the current instantaneous sounding models had not considered the region-changing character of sounding. The paper proposed an instantaneous sounding model, using chart sounding data as static soundings and using forecasted water level based on residual water level correction as dynamic water. Experiments showed that the model realized the fast retrieval of in- stantaneous soundings, and could meet the needs of navigation and military activities in some degree.
