The invention discloses a submarine hydrothermal area sediment distribution simulation method based on topographic data. The method comprises the following steps: step 1, selecting a research area; 2,searching topographic data of a research area and rasterizing the topographic data; 3, judging whether a sunken basin exists in the research area or not, If so, extracting a sunken basin range; 4, analyzing the terrain raster data of the research area to obtain a sediment gravity carrying direction raster; step 5, simulating and calculating a sediment collection quantity grid of each grid; 6, carrying out re-classification and buffer area analysis on the sediment collection amount of the research area to generate a sediment enrichment area; and step 7, delineating a sediment distribution range of the research area. According to the method, submarine topography data information is fully utilized, submarine hydrothermal area sediment distribution is effectively simulated, and the sediment distribution range of a re
