The invention relates to a province-prefecture-county multistage regulate and control joint simulation method. The method comprises a first step of preparing simulation resources; a second step of applying for the simulation resources and deploying a scene; a third step of managing the simulation resources; a fourth step of dispatching the simulation resources; and a fifth step of recycling the simulation resources. Through adoption of the method, the maintenance cost of rehearsal units is greatly reduced, the operation and maintenance response speed is improved, and a large-scale rehearsal can be guaranteed to perform with high reliability and stability.
