Summary:The invention relates to a geometric optics-radiation transmission hybrid modeling method for row-sowing aquatic vegetation canopy reflection, which comprises the following steps: regarding aquatic vegetation with regular row geometric structure, row direction and row spacing characteristics as rectangular box bodies which are uniformly distributed in ridge rows and have certain gaps, wherein a scene in which vegetation canopies and water bodies are alternately and regularly arranged is formed in the direction perpendicular to ridge rows; coupling the model with a plant leaf spectrum model, a continuous medium aquatic vegetation canopy radiation transmission model, a wave water surface reflection model, a shallow water biological optical model and a porous geometrical optical model, respectively calculating the reflectivity and probability of each component in an observation view field, and obtaining the reflectivity of the whole aquatic vegetation canopy after weighting; and exploring the reflection spectrum
