Two-dimensional hydrodynamic water quality model construction method

The invention discloses a two-dimensional hydrodynamic water quality model construction method which comprises the following steps: S1, generating a plurality of leaf grids covering a calculation domain, and dividing the leaf grids into a plurality of sub-grids according to an initial division level of the leaf grids; wherein the initial division level is the maximum division level, and the leaf grid is the maximum grid unit; and S2, establishing a parallel model through OpenMP, and generating a hydrodynamic water quality model adaptive grid in the established parallel model according to the generated leaf grid and sub-grid to obtain the two-dimensional hydrodynamic water quality model. According to the method, the self-adaptive grid generation time can be greatly shortened; according to the method, the two-dimensional hydrodynamic water quality model is constructed, so that the construction time of the two-dimensional hydrodynamic water quality model is shortened, meanwhile, the constructed two-dimensional h
