Guyots are a special type of seamount with flat top and widely distributed in the global ocean. In this paper, geomorphologic classification method for guyots based on multibeam bathymetry data is proposed. By studying typical guyots, namely, Jiaxie Guyots, Caiwei DD Guyot Western Pacific Ocean, study, multilevel system was established, integrating elevation, slope, bathymetric position index (BPI). The successfully classified seafloor geomorphology into nine types: summit platform, extremely steep gentle very gully plain, local crest, depression. Significant differences area distribution, depth characteristics, slope extent different units were revealed by quantitative analysis. flexibility accuracy demonstrated through profile validation comparison validation. This provides new cognitive framework defining boundaries seamounts, as well study genesis mechanisms gullies slopes, crests, depressions formed volcanic activity other actions.
