Contraposing the parameter identification problem of a parabolic partial differential equation with overspecified-data,this paper puts forward the method of using the finite volume element.The numerical solution of the unknown function and control parameters is provided.Then this format has been proved to give good caculation result by the comparasion between the numerical solution and the exact solution of the specific example.
