description The invention discloses a remote sensing scene graph generation method and system based on structured semanteme, and the method comprises the steps: extracting the positions of small-scale and large-scale geographic entities in a remote sensing image through employing a target detection method and a semantic segmentation method, and employing a discrete square grid to generate a remote sensing scene graph; gridding and grid coding are carried out on geographic entity position information in the remote sensing image; performing structured description on the spatial relationship of the target to obtain a plurality of grid subsets generated by geographic entity grid detail division; based on the plurality of grid subsets generated by division, establishing a spatial relationship judgment model, and based on the spatial relationship judgment model, obtaining a topological relationship and an orientation relationship between the geographic entities; semantic processing is carried out based on the obtained topologi
