The invention provides a seismic data anisotropic modeling method based on dynamic correction velocity parameters. The method comprises steps that seismic observation records are read to construct a seismic observation system; a parameter initial model is established and converted to a new parameterization mode (vn, delta, eta, rho); the new parameterization mode (vn, delta, eta, rho) is utilizedto perform forward extension of the source wave field to solve a record residual; the parameterization mode (vn, delta, eta, rho) is utilized to perform reverse extension of the source wave field to solve the gradient; the iteration step size is solved, and the vn and delta parameters are updated; whether convergence conditions are met is determined, and the model is outputted. The method is advantaged in that the new parameterization mode is utilized based on sensitivity analysis, delta parameter sensitivity is improved, recovery of underground anisotropy parameters is facilitated, and imaging and interpretation results for complex geological formations are improved.
