Based on the analysis of the research status of the international submarine geomorphology, the present research trend of China is reviewed, and the research trend of China’s offshore submarine geomorphology is explored. It is pointed out that modern submarine geomorphology of China started lately, but the overall trend is constantly updated with the measurement techniques, from macro to micro, from the landscape type and to a specific landscape, in-depth study, with an emphasis on the relationship between human activities and geomorphic process. The achievements, new discoveries and new knowledge of the submarine topography and geomorphology in offshore China are introduced emphatically in the light of “Investigation on Submarine Topography and Geomorphology in Offshore China(908)”: The Yangtze River sand ridge group of ancient tide outlets can be divided into the accumulation of the ancient trend, erosionsand ridge group of the ancient tide up sand ridge and erosion of the ancient tide sand ridge group of three types; In the Minjiang River mouth of Fujian offshore islands between Matsu Island and White Dog Island, more SWNE strips are found of distribution of sand ridge, with an area of about 200 km2 and sea water depth of 15 to 30 m; In the East China Sea continental shelf sand ridge area outside Taiwan two new submarine rocks are found. These new findings and knowledge in the research of the landscape in offshore plays a great role in the promotion and improvement of the research of offshore submarine geomorphology.
