摘　　要：海底地貌数据与人类认知海洋、探索海洋、利用海洋息息相关,海底地貌数据综合是海图编制、海洋空间数据处理的重点研究内容之一。海底地貌数据综合属于地图综合的研究范畴,但受历史渊源、学科体系、应用范畴等诸多因素影响,常被认为是地图综合中相对独立、特殊的研究内容。本文在明确海底地貌数据综合特殊性的基础上,从数据增强、综合方法、质量评价3个方面梳理海底地貌数据综合研究进展,归纳了几种常见的海底地貌数据综合应用案例,并从研究内容、技术方法、实践应用3个方面探讨了海底地貌数据综合的发展趋势。The submarine terrain data influences human cognition,exploration and utilization of the ocean largely.The generalization of submarine terrain data is one of the key researches of nautical chart generalization and oceanographic spatial data processing.Usually,the generalization of submarine terrain data belongs to map generalization.However,influenced by many factors,such as historical origin,disciplinary system,application target and so on,the generalization of submarine terrain data is often regarded as a relatively independent and special research content in map generalization.In this paper,the specificities of submarine terrain data generalization are explained at first.Furthermore,the development of submarine terrain data generalization is summarized from three aspects,i.e.,the data enrichments,implementation methods and quality evaluations of submarine terrain data generalization.And then,three common use cases of submarine terrain data generalization are given.Finally,the development trend of submarine terrain data generalization is further discussed based on its content deficiency,technique upgrading and application prospect.
