摘　　要：海底地形地貌分类是海洋地质学研究的重要内容之一,分类方法需要结合多学科知识完成。海底地形地貌中典型地理实体类型的界定也是海底地名命名研究的重要内容之一,直接关系到海底地名的准确性。国际海底地名命名分委会(SCUFN)在此领域已进行了多年的研究和探索,总结出了包含54类海底地理实体类型的海底地名通名列表。但由于命名方法的限制,目前SCUFN有关地名通名的界定原则多局限于对地理实体外表形态的判别,较少考虑其地质成因和构造性质,这也造成了许多地名提案出现了审议—通过—推翻—重新审议的情况。在分析海底地形地貌类型的基础上,总结现有的海底地理实体分类方法,并针对海底地名命名出现的地理实体类型界定争议,说明SCUFN分类方法存在的缺陷,力求寻找更加科学准确的海底地理实体界定方法。Submarine geomorphology classification is an important job in marine geology research. The re-search of submarine geomorphology classification method needs marine geology, marine sedimentology, marine geo-tectonics and others. In the field of undersea feature naming, generic term represents the type of undersea features.Therefore, defining the undersea feature＇ s type also relates to the accuracy of the undersea feature names. TheSub-Committee of Undersea Feature Name （undersea feature naming, has been engagedSCUFN）, as the only official international cooperation organization inin this field for many years. It mainly focuses on the generic names andspecific names of the undersea features. Until now, SCUFN has divided the undersea features of global seas into 54types and published officially the《 Undersea Feature Terms and Definitions》, which includes the 54 generic terms ofundersea geomorphology, and explanations and examples of every type of undersea features in the publication.However, because of the restriction of classification method, SCUFN only focuses on the appearance of underseafeatures in confirming the generic terms, ignores the geologic cause and geotectonics attributes. In the developmentof ocean exploration technology, the higher precision bathymetric data of submarine geomorphology have been ob-tained. The traditional method to define the generic names of undersea features already reveals its defects. This re-sults directly in many proposals of undersea features experiencing the process of proposing-discussing-accepted-over-throw-rediscussing in SCUFN. To promote the development of undersea feature naming, the higher accuracy methodof undersea feature classification will be needed. In this paper, the types of submarine geomorphology will be ana-lyzed. The popular ways of undersea feature classifying will be introduced. Some proposed dispute examples duringthe SCUFN discussion will be introduced. The aim is to find a proper way to define the kinds of undersea features.
