The invention relates to a grid-type hydrological model grid calculation order coding method based on DEM, which comprises the following steps: determining grid size, obtaining grid flow direction, dividing river channel grid and sub-basin, sub-basin coding, confluence layer coding, layer sequence coding, inflow grid coding and river channel coding. According to the encoding method of the invention, it can realize the calculation of runoff yield and concentration of grid hydrological model. The coding rule assigns different identification values to each sub-watershed of the watershed, which facilitates parallel computation. In the coding process, the river mesh and non-river mesh are distinguished, and the hydraulic connection between the mesh occurs only between adjacent layers, which facilitates to find the problems in the calculation process according to the topological relationship through the coding rule in the calculation process.
